Aviation Enthusiasts! NASA Snaps pictures of Supersonic shockwaves of 2 T-38's VERY cool!

NASA's mission to capture air-to-air images of supersonic shock waves was a long and fraught process that lasted more a decade. But now, the space agency has accomplished the task with flying colors.

On Tuesday, NASA released a series of stunning images that show two T-38 supersonic jetliners tearing through the atmosphere, creating sonic shock waves. The images were made possible by a NASA B-200 King Air aircraft, which ferried an updated camera imaging system up to 30,000 feet. At altitude, it followed the jets from a distance of 2,000 feet, snapping their trek through the sound barrier at 1,400 frames per second.

“I am ecstatic about how these images turned out”

The T-38s flew in tight formation, separated only by 10 feet. Documenting their burst through the sound barrier from such a close vantage point will help NASA accrue more data on supersonic shock waves than ever before, which is a pressing matter given the potential resurrection of supersonic passenger travel.


From here

3. Does this create sonic booms?

When I was a kid we heard those all the time.

4. I imagine it does, yes.

In the early oughts I lived in Palmdale, CA, home of the Lockheed “Skunk Works” and right across the valley from Edwards AFB and the NASA flight research center (used to be called the Dryden research center but they changed the name to honor Neil Armstrong) and heard sonic booms on a regular basis.

10. Yeah.... being a pilot and aviation nut those things bug the shit out of me.

T-38s are rather small supersonic (barely) trainers, definitely NOT a jet-liner. The photos are fantastic, but the writing could stand to be more technically correct (And you'd think that Popular Mechanics could do better).

16. Let me explain how this post came together

I subscribe to a weekly email newsletter from "FlightAware". Their link accompanying the story was to the Popular Mechanics piece. Inside that story is the NASA source story which I linked in my OP. Reading the NASA write up on the event makes clear the writer is knowledgeable and uses the proper terms.

I am and have always been an aviation enthusiast. I don't have a pilots license, but I have always loved and been fascinated by aircraft of all types. I put up posts like this on occasion and I endeavor to get things right.

My apologies for any confusion.

12. Yes! Not my text, thankfully!

It always bothers me when some TV commentator or writer who clearly has no clue, goes on about something like this and uses incorrect nomenclature. Don't they have editors who are supposed to consult someone who knows this shit?

Yeah...no doubt....the T-38 is about as far from a Jetliner as the Wright Flyer is from a DC-3

13. That's a cool vid and one of many, but not all those planes are breaking the sound barrier

The Blue Angels flying over San Francisco Bay are generating what's known as a "Vapor Cone" or "Shock Collar", which is particularly impressive, but not necessarily an indication of supersonic airspeed.


A couple of those passes at sea between or near ships are indeed +700 MPH flybys
Either way, it is cool footage, no doubt.

11. That's amazing. Sonic booms were a regular feature of life when I was a kid in the early 50s...

Was just thinking the other day I haven't heard one in years.

14. One of the things that killed the likes of the Concord....

was the almost universal opposition to them flying over populated areas at speed.

NASA and others have been trying for years now to develop air frame shapes and aircraft that will produce no or nearly no sonic boom.

It's my understanding that when the British Airways and Air France Concords took off from JFK, the pilots couldn't "firewall" the throttles till they were well off the Eastern tip of Long Island.

18. I still hear them once in a blue moon, flyboys get carried away & I'm sure get reprimands.

Its been a few years, the biggest one was back in the 80's, got everyone outside looking for the tree that fell on the house

26. While on my morning walk I heard a strange whine/roar over head

Living near two large and one small airport I hear all kinds of piston, radial, jet and helo sounds but this was different. I scan the sky and it was two F/A 18's flying in formation heading for the coast.. The closest military base is down in the key's if I remember correctly
Neat very distinctive sound.. They were going slow over residential area so no "boom"...rats.

But in none of those pictures do they have a 10 ft separation. (the article's words, not yours)

24. I know.

The NASA write up is much clearer.

The pertinent paragraph;

The images feature a pair of T-38s from the U.S. Air Force Test Pilot School at Edwards Air Force Base, flying in formation at supersonic speeds. The T-38s are flying approximately 30 feet away from each other, with the trailing aircraft flying about 10 feet lower than the leading T-38. With exceptional clarity, the flow of the shock waves from both aircraft is seen, and for the first time, the interaction of the shocks can be seen in flight.
