How do we lose an airplane

This whole missing airplane thing freaks me out because I didn't think it was feasible to even lose an airplane. Yet this one just seems like it vanished in mid-air.

Anyone else freaked out over this?

It seems to me that "big enough to make the search even more difficult" is all that is needed.

It's also not clear if local conditions (clouds, haze) could be limiting visibility. I'm sure the people doing the search know the answer to that, and how the currents in the area might disperse floating debris, and what resources they have on hand to conduct the search, but they aren't part of this speculative discussion.

There are signals that are sent from transponders and an ELT - a floating GPS beacon. And a mid air explosion should have been picked up via satellite.

None of which seem to be transmitting. It is very odd.

Using Wikimapia's distance measuring tool, it is 240 miles across the Gulf or Thailand on the track the plane was taking in your photo. 240 miles across the narrowest point.

That's about the same distance from Chicago to Detroit as the crow flies, or 40 miles less than the distance from NYC to DC.

seriously. everyone keeps reasoning and you seem to be insinuating that this is some sort of impossible conspiracy.

What 'impossible conspiracy' am I insinuating?

That I'm surprised that they haven't discovered one trace of the aircraft yet? I am. So are a lot of experts.

My whole point is that the plane didn't go missing in the middle of a vast ocean. It didn't. That's just a fact. I

that it's automatically easy to find.

it's not.

there are three axes to search, latitude, longitude and depth.

and it's not one giant plane we're looking for, it may be minute pieces, or if it is a giant contained wreckage, in hundreds of miles of sea floor.

at some point, the obtuseness crosses a line.

to be sitting in thousands of feet of water. The Gulf of Thailand is 250 feet at it's deepest. Of course it *could* have gone that far off, but wouldn't it still have been on radar if it had? And if it had, that doesn't point to a sudden, catastrophic event.

how close does one need to be to get the signal, and if one is close enough to detect the signal, how easy is it to find it once it's detected?

If its underwater the detection range is about 2 to 3 kilometers. So on the scale of an open water search, you'd have to be pretty damn close.

162. Judging by your posts, you are assuming exactly where it went down. You cannot.
Mon Mar 10, 2014, 06:51 PM
Mar 2014

Because no one knows where it went down, only where it lost contact.

At altitude, if there was a problem, and if they could not contact air traffic, the pilots would have to make a decision on what to do... Continue on the flightpath, turn for the nearest land, re route to another airport along the flight plan, etc... If they had been flying for just 60 seconds after that last contact they could have traveled over 9 miles from where the last contact was. This can make a huge difference in the search area (254sq miles), and every minute aloft could simply add more and more distance to the search area.

If a 777 loses power at altitude, the simple 1:15 glide ratio could be used to determine how far they could travel. Which works out to just over 100 miles. And then you can add to that the distance traveled after they lost contact.

So for a mental exercise lets say the plane has lost contact and flew for an additional 120 seconds before it lost engine power. The pilots made the decision to turn 15 degrees and head towards Ngọc Hiển (south Vietnam). The plane then crashed after stalling out at the end of its glide. Now if you limited your search area to the point of last contact you would be looking at an area of about 31,400 square miles just to cover any and all given glide directions from when the plane lost contact. That is about the size of South Carolina. However, since the plane took a new route 120 seconds after the last contact, your original search area would result in you finding nothing. You would need to add an additional 12,000 square miles to your search to the north and east of your search area. So in order to find the aircraft you would have to search an area larger than the state of Virgina.

31. There are the engine monitors, for example
Mon Mar 10, 2014, 12:52 PM
Mar 2014
Rolls-Royce, which made the plane's engines, told the Post it was sending investigators all information it had from its systems which monitor in-flight engine performance.


http://www.scmp.com/news/asia/article/1444784/china-urges-malaysia-step-search-missing-passenger-plane-families-grow

However, Rolls-Royce does not just sell engines. These days customers want the services to look after engines on the wing; 24 hours a day, 365 days a year, anywhere in the world.

The company’s services business is built on the intelligent use of a phenomenal amount of data. Rolls-Royce typically measures around 20 performance parameters on a Trent engine such as vibration levels, oil pressure and temperature. The company has about nine gigabytes of data per day streaming into their data centres, which equates to half a billion data reports a year. The data is analysed as it flows in, with trends extrapolated and anomalies detected. It not only gives the company early warning on fault diagnosis, but equips it to help its airline customers to schedule maintenance more cost efficiently.

The Rolls-Royce Engine Health Monitoring Unit is an extremely complex software set that takes signals from dozens of sensors around the engine and transmits the data via satellite while the aircraft is in flight. The company’s service engineers are therefore alerted to potential issues early, in advance of them causing an operational problem to the airline. If repairs are necessary, the company can have a field team standing by on the ground by the time the plane lands. In this way Rolls-Royce is saving the customer down time, minimising disruption, keeping the engine in service, and keeping the passengers flying.


http://innovationnow.raeng.org.uk/innovations/default.aspx?item=15

I haven't seen how often the data is satellite linked back to Rolls.

Mon Mar 10, 2014, 01:51 PM
Mar 2014

If both engines simply tore off the aircraft, the sudden power loss would force the RAT into the airstream, providing both limited hydraulics and electrical power to the cockpit. The 777's APU would also immediately start powering up and would restore full power and hydraulics to the aircraft in under 30 seconds. The aircraft is capable of communicating with the outside world using power provided by either of these systems.

Losing the engines alone wouldn't be enough to prevent the crew from sending a radio broadcast, because the aircraft is redundant enough to account for that. A catastrophic airframe failure on the other hand...

I'd think it somewhat likely that the wires would be damaged in such an event, and since the airplane's conductive, a short would be likely. I don't know if there's something in the electrical system to electrically cut off the now-cut wires.

But as you mentioned, an airframe failure is far more likely than "both engines fell off".

Mon Mar 10, 2014, 01:49 PM

There is a series of shows called Air Crash Investigations, or Mayday, or Air Investigations depending on the nation where it is shown. Many of these episodes are available on You Tube.

Many times there is no call because the pilot is very busy trying to fly the plane. Air France flight that went down in the Atlantic a few years ago. The pilots are discussing the problem, and trying to fly the plane, and never made a call. Similar accidents have happened many times. The pilots were just too busy to make a radio call.

When you are making a call, you're supposed to tell the controllers what kind of a problem you are having. With alarms going off and screaming at you, it may be difficult to diagnose the problem as it is. Discussing the details of your efforts with ATC may slow you down.

China Air flight 006 did not respond to several calls from ATC while they were struggling with the problem. Once they had the plane more or less stable, they made the call declaring an emergency.

The Gimli Glider had to wait until the emergency impeller generator deployed before they had radios working to report the problem of running out of gas in midair. They had reported being low on fuel, and then they were off the air.

So the absence of a mayday call shows only that the pilots didn't have time to inform anyone of what was going on, the plane may have suffered a catastrophic incident, like the airplane that exploded over Long Island Sound, or the United Jet that landed better than could be hoped at Sioux City with no control after an engine explosion took out all three of the hydraulic systems.

Taca Airlines flight 110 could not report to ATC what was going on until the APU was started, an event that took more than two minutes. BTW, that is one of the best emergency landings ever. That accident taught us that the engine design on the 737 was not as good as we had thought, and a redesign/modification was needed to make the engines safer.

Before the pilot can report what is going on, he/she has to do the first thing that they are paid to do. Fly the fucking plane. If they can't do that, then they're not going to waste precious time reporting that they're going in, they're going to be fighting to the last second to make that plane fly.

We have to find the Cockpit voice recorder, and the Flight Data Recorder. They provide a lot of information on what went wrong. The alarms that sound are caught on the voice recorder. The position of controls is found on the flight data recorder. With that information, you can be 80% sure what happened. Using that information, you know what parts of the plane are absolutely vital to be recovered.

BTW, the China Air 006 accident started when an engine failed in flight. The cause of the engine failure was determined to be a worn throttle linkage that was worn a few thousandths of an inch beyond specifications. In other words, a part that was worn a little too much caused an engine to fail. A mistake by the pilot led to a plane nearly crashing into the ocean.

A failure of a component could easily bring the plane down. Just look at the DC-10 problems with the cargo door. http://en.wikipedia.org/wiki/McDonnell_Douglas_DC-10#Cargo_door_problem

Right now, we don't know what brought the plane down. We need to find the wreck, and the black boxes, in order to learn the truth.

Maintenance could be a problem too. Chalk airlines suffered maintenance problems that led to a catastrophic accident in Miami Harbor.
http://en.wikipedia.org/wiki/Chalk%27s_Ocean_Airways_Flight_101

I hope this gives you, and others, the briefest of overviews of the kinds of accidents that can happen, and how the pilots are often rather busy trying to fly the plane, and just don't have time to say the magic words Mayday.

165. A charter jet flew off of San Juan once
Mon Mar 10, 2014, 07:21 PM
Mar 2014

The plane had been sitting for a couple weeks, and was chartered to support an airline that was overbooked. This jet was flown by two experienced pilots, and everything looked just fine for a nice simple flight. Only unbeknownst to the pilots the Pilot's Pitot tube was blocked. In the air, his air speed readings started coming up, and he thought the problem was fixed. Next, the plane started to warn of over-speed, and the stick shaker kicked in warning of a stall. The pilot ignored the stick shaker, and throttled back to deal with the over-speed. The plane slammed into the ocean belly flopping to it's doom.

The investigators never found the pitot tube, but the believe that a wasp built a nest in the tube, blocking it. When the plane went up, the difference in pressure caused the tube to give false readings on airspeed, causing the over-speed alarm. The stick shaker was the most important warning, the plane was stalling, and the pilot ignored it in favor of the over-speed alarm to the sorrow of so many families.

No mayday call was issued, the pilots were busy trying to get the damned plane to fly right. That they misdiagnosed the problem was the human error element of the crash. A plane load of people died because a wasp built a nest in a pitot tube and the pilot paid attention to the wrong warning and ignored the most important one.

There have been so many air accidents, and so many lessons learned. I was talking to my neighbor, who is a pilot, while I am an interested observer. The rules of flying, of airplane design, of piloting the aircraft are written in blood. We learned what not to do by studying the accidents, and learning from them.

I don't know what brought down the Malaysian airlines flight. I do know it is vital to the safety of every person in the sky that we find out and see what lessons can be learned. If it was terrorism, a possibility, but I won't call it probability just yet, then we need to look at why it happened. Most nations have gone to "biometric" passports, which means that identifying information on the individual is coded into the passport. Apparently, nobody thought that someone would steal a passport, and honestly, I'm not surprised someone did.

Allow me to explain. Normally, the close examination of the passport takes place at the destination, not the origin of your travels. They may ask you if you have it, and they may glance at it to make sure it is not expired, but even our TSA (Totally stupid assholes) and our CBP (Complete Blithering Pecker-heads) don't examine the passports all that closely if you are leaving, unless you're on one of the many watch lists which normally identify everyone but a terrorist.

It could just as likely be minor failures of important instruments (not sure if minor is the right phrase) leading to special disorientation and controlled or un-controlled flight in to the ocean. That could very well be the reason for no mayday calls - the pilots were having some problems and too busy flying.

Minor survivable problems have led plenty of controlled flight in to the ocean at night where there are no visible cues to sight and orientation.

216. The Air France flight that crashed a few years ago.
Tue Mar 11, 2014, 03:55 PM
Mar 2014

The cause of that was catastrophic human error. The pitot tube froze in bad weather. The autopilot could not fly the plane without speed imput from the sensors. The autopilot threw up it's virtual hands and told the pilots "I'm out, you have to fly."

The pilots did the wrong thing. They did not fly the plane, they focused on the problem of the air speed information that was missing, and the autopilot. The copilot pulled back on the stick, causing the plane to go up, and then it stalled. Air was no longer flowing across the wings to provide lift.

The computer recognized a stall in progress and told the pilots over and over again. Stall, Stall, Stall the computer repeated the entire time the plane was falling, for almost five minutes, both pilots heard the warning bells and the computer chiding them with that word. Stall. But the copilot held the stick back until the plane hit the ocean. They were dropping at 12,000 feet per minute as they hit the water. Simple problem, compounded by human error.

I'm torn. I like technology, and think it is great. But, we become dependant on the technology. The pilot becomes accustomed to things working right. I can imagine the pilot thinking he's flown thousands of hours in this kind of plane and nothing has ever gone wrong. he becomes complacent, relaxed, comfortable. Then when the computer kicks out and says fly the plane human, the pilot has to start thinking immediately. They have to shift from all is well to holy crap what is going on in less than a second. The first question going through their minds is almost certainly what is wrong with the computer. Not what is wrong with the plane, but what is wrong with the computer.

Quantas flight 32 is a great example of that. The engine blew up, and the pilot did the right thing taking manual control immediately. Then he flew straight and level while they determined the problem and how bad it was. The co-pilot spent the next 55 minutes going through all the warnings on the computer one by one and acknowledging the problem, or authorizing a computer work around, that didn't work.

They worked the problem for 55 minutes while flying a plane that had suffered a catastrophic engine explosion. They flew for 55 minutes with a hole in the wing leaking fuel while they acknowledged what they knew a minute after the explosion. The god damned engine blew up and we need to land the plane as soon as possible or we are all going to die.

They could not start anything else until they had acknowledged the computers long list of problems. Then they still had to do what they could have been doing 55 minutes ago. Easing the controls around while they found out how badly the plane was hurt and how much control they had.

On the ground, the crew found to thier dismay that the engine cut off was not working, due to the damage to the wing. So they could not shut down one of the engines. The chief engineer at Quantas suggested squirting water into the engine to make it fail. Engines are designed to work in that very situation. After an hour of firetrucks pumping water into the engine to no avail, they decided to try firefighting foam. That extinguished the engine, making it safe for the firefighters to approach the plane and deal with the fuel leak.

Taca Airlines flight 110 exposed the problem of plane engines not working like they are supposed to when throttled back, and the engines were redesigned for that problem. There was no way on earth that a firehose would make it to the combustion chamber and extinguish the flame even at idle. The engine is designed to spit the water out long before it gets to the flame.

Computer assisted controls sound like a good idea, but I have believed for a long time that true piloting skills are lost every hour the computer is controlling the aircraft. You can't help but get complacent, comfortable. Then when an emergency happens, you spend too long trying to figure out what the computer is doing before you start to think about the plane. Precious seconds are lost while you are asking the normal question. What the hell is going on?

at that resolution, the field of view is so small that only a very tiny patch of ground is seen.

Satellites are not search platforms - they are given very precise coordinates to point their sensors at.

A more practical issue is that I am sure there are much higher priority things they want satellites looking at.

Let's say that you had it narrowed down to a ten mile by ten mile area.

That's a hundred squares, a mile on a side, and, even if the plane wasn't on the bottom of the ocean, you would be looking for an object that is 242 feet long.

But all one is looking for here, in an ocean full of waves and whitecaps are small pieces of floating debris.

A ten minute window gives you about a 100 mile path of ocean to cover. And remember, the aircraft could be deep into the sea. I don't know what the speed at impact would have been, but from 35k feet it's safe to say if the plane were somewhat intact it's deep into the ocean.

36. the difference between passive and active sonar --
Mon Mar 10, 2014, 12:57 PM
Mar 2014

with active sonar, you can create a very, very loud "ping" and yes, listening devices can hear it and its echoes across vast distances.

passive sonar is listening for noises without a ping, relying on the sound of the "splash" in this case to propagate in the water -- this is much, much quieter than those "pings" that travel vast distances, and you need to be very close to detect it.

the fact that the noise is at the surface also makes it more of a challenge, as does the actual frequencies of the sounds involved (low frequencies travel better, a splash would produce mostly higher frequencies).

29. This is an interesting question.
Mon Mar 10, 2014, 12:48 PM
Mar 2014

When they lost the french plane in the sough pacific they pretty much knew where it was and found wreckage within a short time and that was in very bad weather. That plane was found on the ocean floor and the water there was much deeper than in this incident.
The water in the area that this plane went off of radar is about 600' deep. We can get down that far with many different platforms. So if it is there we will find the plane.
If it had crashed in one piece into the water it would have come apart leaving a more compact area of floating wreckage and oil slick.
If it had blown up or disintegrated in mid air the wreckage field would be large. In either case there would be a visible field of wreckage that should have been found.
That leaves room for speculation.
It hit the water in a more controlled manner and did not break up. This would mean that there was time for "mayday" alerts. There were none.
It had flight handling problems and veered sharply away form its course and continued to fly out of the area and then destructed in an area they are not searching. This too would have given the crew more than enough time to sound the alarm.
The pilot caused some deviation of course and then put the plane into a vertical dive leaving a very small field of wreckage in an area that they are not looking.
OR. It was taken and not lost. Maybe taken because someone needs a 777 for another venture. Who knows. I don't.
All of this is pure speculation. Nothing in this makes since right now.

Plus, I learned in Physics (granted, many years ago) that water was basically incompressible, and thus it's density does not change with increasing pressure at depth. Otherwise, scuba diver's bodies (being mostly water) would crush as they descended even a couple of hundred feet.

But, what do I know? I was more of a radar guy, not sonar.

Mon Mar 10, 2014, 01:59 PM

to look at.

If you've ever used a SLR camera, you know that you can focus it in close on a flower, but if you move the view up and away to say....the door of your neighbors house 250 yards away, it is a complete blur.

The satellites are basically the same. I've spent a fair amount of time looking at Google Earth sat shots and the focal length diffrences are dramatic. They could be taking a picture of something and an airplane could fly right through the shot and not be seen, because the camera is trained on ground level, not at 30,000 feet above.


The planet is just too vast, the number of airplanes, as mentioned by others, is too numerous and the number of ground photo satellites too few to do anything close to what you suggest.

There would be a rain of small-to-medium-sized pieces over a very wide area (many tens of square miles). Most fragments would sink, and the rest would be very difficult to spot. It's not a "plane" any more, it's now an underwater debris field. The difficulty in locating any wreckage seems very logical to me - there are probably few large chunks of the aircraft on the surface.

Mon Mar 10, 2014, 02:07 PM
Mar 2014

Every cushion on a modern aircraft floats. So does paper. So do bodies. So will a lot of luggage. So does most of the insulation. If the aircraft broke up at 35,000 feet, there would be a very large and VISIBLE field of smaller floating debris that would be quickly picked up by search planes.

The fact that there isn't would suggest to me that the debris field is much smaller. THAT points to the aircraft hitting the water intact. I'd imagine a scenario more akin to United 93, with hijacking followed by a dive into the ocean. Remember how little debris there was at the United 93 impact site? The debris field was relatively small because the aircraft struck the ground in one piece. Something similar would happen in a water strike.

Heck, an even better comparison would be that Valujet flight that went down in the Florida Everglades in the mid-90's. It hit the water in one piece and there was almost NOTHING on the surface to indicate that it was a crash site. The first people to arrive on the location at ground level had to get confirmation from the helicopters above that they were at the right spot, because it wasn't even apparent that they were floating a few feet above the wreckage.

They're extremely rugged, yes, but they will be destroyed by an extreme-enough crash. IIRC, the boxes did not survive the 9/11 flight that crashed in PA.

As for the transponder, it's not just a matter of "turning it up". Doing so has repercussions on the survivability of the box. You need a larger battery. You need a larger speaker. You need a more powerful amplifier. You need a larger antenna.

The conspiracy theory is that it was shot down.

Problem is a mid-air explosion would cause the plane to break up in the air, and spread a large debris field. And not destroy the black boxes, because the impact would be slower - broken airplane chunks have much more drag than intact airplane.

OTOH, someone pushes the nose down and flies it full-throttle into the ground, and you get the relatively small impact site, and destruction of everything. Including the black boxes.

there are very few cases where all boxes are completely destroyed. Three were more losses back when we literally used recording tape, but for the past 15 years or so it has all been solid state. These boxes are located fore and aft, so it is very unlikely that boxes from both ends of the craft would be completely destroyed. The more common problem is that they simply aren't located, especially when talking about ocean crashes.

Mon Mar 10, 2014, 06:00 PM
Mar 2014
http://en.wikipedia.org/wiki/List_of_unrecovered_flight_recorders

Notice there was not a single case where both boxes were destroyed. There were two cases where one of the two boxes was destroyed by fire, not by the impact of the crash or explosion and one case where the tape was broken and partially unreadable. All the other problems were cases where the boxes were simply never located.

Moreover, that chart doesn't show the recovery time. In some cases, it was months or years later. Engineering a better beacon technology would give everybody a lot of comfort, not having to wait so long to discover what went wrong.

161. Both the flight data recorder and cockpit voice recorder survived the flight 93 crash in PA
Mon Mar 10, 2014, 06:03 PM
Mar 2014

The voice recorder was buried in the ground about 8m below the impact crater, but they were still able to recover it.

They are very good at surviving a crash. What they are not so good at surviving is prolonged heat exposure. The voice recorder from the Pentagon crash was recovered, but the magnetic tape was melted into a solid block and was unusable. Likewise, the recorders from the WTC impacts were destroyed by the extreme, prolonged heat of the fire.

It is almost certain that the recorders would have survived an ocean impact.

Spy Sats, Google Sats, NASA etc etc etc.. with all the technology in the skies and on the aircrafts... there's no way that our government (and likely other govt's) isn't aware of the location of that plane. It didn't just "vanish" from their "radars"..

It is curious, why they're being silent and feigning ignorance, though.

If we had that kind of satellite coverage, we wouldn't need the NSA monitoring us because the satellites would just pick up the phone number you dialed on camera...

Seriously, we DON'T have that kind of coverage, and while satellites can be repositioned, there's still a hell of a lot of water to cover.

We've had capability in place long before the launch of the GeoEye1.

All I'm saying is the technology not only exist, it's been in place for a number of years.

Which begs the question, why are we being silent on this event?

As I said in post #81, you have to know where it is you want the satellites(s) to look and when, not to mention the exact altitude.

The satellites mentioned in the link of yours are not focusing in on every square meter of land and water 24/7. They make passes. They orbit. They have to be told which way to point their cameras and how close in to focus. As I indicated, they could focus in on say... a fishing boat in the ocean and a jet could fly right through the shot at 30,000 feet and not show up in the photo.

NASA Joins Hunt for Missing Malaysian Passenger Jet



Activities under way include mining data archives of satellite data acquired earlier and using space-based assets, such as the Earth-Observing-1(EO-1) satellite and the ISERV camera on the International Space Station, to acquire new images of possible crash sites," NASA spokesman Allard Beutel told Space.com via email. "The resolution of images from these instruments could be used to identify objects of about 98 feet (30 meters) or larger."

In addition, Beutel added, NASA will be sending relevant data to the U.S. Geological Survey's Earth Resources Observations and Science Hazard Data Distribution System, which facilitates the sharing of information whenever the International Charter on Space and Major Disasters is activated.

And probably still are? You don't re-task sats for non-national security issues, esp involving a foreign airline overseas. They'll find it eventually. Might take some sonar and mini-subs though. Not sats. And lots of areas out side of the US have little or no radar coverage.

Spy Sats are designed to focus on small spots on the ground...that is what they do.BY DESIGN they don't do large areas.With ANY camera you have two choices...wide field or up close focus.A spy sat that did wide field views would be worthless as a spy sat.

Mon Mar 10, 2014, 03:00 PM
Mar 2014

Most civilian radars do not actively search the skies. They look for and track transponder signals, which every plane has. If there is no transponder signal, then to civilian systems, you might as well not exist.

It's only military radars that can actively search for and track a plane with no transponder (or one that's been turned off).

I think there is a history of missing airplanes back in the last century that were never found. It's just today, we have global news in minutes, so it doesn't take weeks for a story to get out. I actually know of one passenger DC 7 that disappeared over the Pacific off the coast of Peru in 1948 but because it was not an American airline with American passengers in it, it was local news only. No trace of the airplane was ever found. Maybe someday it will be found by divers now that our diving equipment is more sophisticated and can dive at deeper depths. They could find it accidentally though looking for something else. So the chances of it being found are pretty much zero in this day and age.

158. This article may help explain it for you. AF447 took 5 days to find any wreckage.

http://www.nytimes.com/2014/03/11/world/asia/malaysia-missing-jet.html
(clip)
So far there is only speculation about what happened to the missing flight, which was headed to Beijing from Kuala Lumpur. But Arnie Reiner, a retired captain with US Airways and the former chief accident investigator at Pan Am, noted, “If they somehow got turned around or went off course when the thing was going down, it could be 90 or 100 miles away from where the flight data disappeared.”

It is not yet known whether the Malaysian plane deviated from its planned flight path, or how long the pilots could still fly the aircraft after the last reported contact. Assuming that the plane remained in powered flight or a controlled glide, the potential search area would have to be wide and long, covering thousands of square miles. After more than two days of fruitless search, Malaysian officials expanded the search area on Monday.
(clip)

But extended searches are sometimes needed. When Air France Flight 447 vanished over the Atlantic in June 2009, it took five days to find any wreckage, and almost two years to find the black boxes. Similarly, the cockpit data recorder from a South African Airways Boeing 747 that went down in November 1987 was not located until January 1989. It revealed that the plane crashed because of a fire onboard, not because of an act of terrorism, so no further search was conducted for the flight data recorder, the other black box.

Another rule of thumb for pilots may shed light on why no distress signal was heard from the Malaysia Airlines flight. Pilots have a mantra for setting priorities in an emergency: Aviate, navigate, communicate. The first priority is to fly the airplane. Telling air traffic controllers on the ground what is going on comes third, since doing so is unlikely to instantly yield any help with the crisis in the cockpit, whatever it is....(more)

It's location was known, though it drifted downriver as it sank.

It still hasn't been found, let alone recovered.

If the US military, civilian searchers, civilian salvage operations and amateur aircraft enthusiasts working for 58 years can't find an intact military aircraft in a known stretch of river somewhere near Pittsburgh, can you imagine how much more difficult finding aircraft bits in the South China Sea would be?

Without radar or an effective radar system, a plane can vanish. Radar systems in the countries that the plane was traveling through aren't as advanced as the systems used in the US and Europe.

If the plane fell in the ocean, it's not very deep water (around 200 feet plus). By comparison, the Air France plane that fell into the Atlantic was in 13,000 feet and they found it right away.

I think that maybe the plane was not on course and that's why they are not finding any debris.

201. We lose an airplane for 2 really simple, stupid reasons
Tue Mar 11, 2014, 01:36 PM
Mar 2014

1) We build planes in a way that allows the pilot to turn off the transponder. That makes no sense. That thing should be on as long as the plane is in the air, not just for these cases, but for everyday safety concerns. It is stupid to allow a design where a pilot (or hijacker) can turn it off.

2) We have an air-to-ground communication network for passing all sorts of information that helps the airline run the day-to-day business. We should be mandating that the essential aircraft status information (in a distilled form that won't overload that network) be automatically transmitted in real time as long as the aircraft is in the air. Some airlines use this capability, but there is no indication that was an available source in this case.

If we had these two things, we would have known what was happened BEFORE the plane crashed (assuming that it crashed.)

Tue Mar 11, 2014, 03:07 PM

The transponder should be off at any point while the plane has power.

The A2G network does exist, however that is only over land. There are a lot of dead spots over open water. They have looked at this, and it does indeed exist in various forms on several newer aircraft, but the coverage does not exist. Satellite is an option, however the annual bandwidth per aircraft would be astronomically expensive. To the point that even small packets of data with the vitals of each aircraft could warrant it's own satellite network. There are about 94,000 flights per day in the world.

 

BlueStreak

213. Even minimal vitals would be a huge step forward
Tue Mar 11, 2014, 03:18 PM
Mar 2014

And that should not be prohibitively expensive over satellite. Something like every 60 seconds send out a packet with GPS coordinates, altitude, airspeed, and a summary of each major system. That would not be a lot of data and it would give investigators an instant view of what happened -- at least what kind of scenario is involved. Here we are just guessing 4 days later, and evidently the authorities are not much better informed than we are because they didn't expand the search to the Strait of Malacca until less than 24 hours ago. If there was a water landing with survivors, they would have been in the water for 3 days by that point.

Is this really the best we can do in 2014?

With the right amount of corruption or influence, the plane could have been purloined for nefarious reasons. Religious ruling leaves a lot of leeway for activities that pertain to religious beliefs.

Tue Mar 11, 2014, 11:07 PM
Mar 2014

Why were the transponders shut off? Why did it completely change course after? Why has this information been released several days after? Who were these men with stolen passports (yes, we have identities, but I still think their background needs greater research)? Who is the travel agent dealing with them in cash? I also heard something about some other passengers that cancelled at the last minute but their luggage may have been onboard...I haven't heard much more about that. The Malaysian government's/airline's response has not been particularly transparent either, likely out of fear of embarrassment due to the their lax and incompetent (and possible corrupt) security. I wouldn't be surprised if someone accepted some bribes. Corruption is rampant.

But we first need to know where the hell the pieces of this plane are....I hope we get answers soon.
