Dust trails from WTC debris during tower destruction

[spooked911]

I find it very striking the way thick trails of dust are trailing from the large chunks of debris here:


The right hand circled debris is very strange, as there is a huge dust streamer coming from a relatively small piece of debris.

To me, this trailing dust indicates demolition-- a massive explosive force is pushing out the steel columns and disintegrating all material that was between the outer columns and the explosive, and this disintegrated material is trailing the columns as thick dust.

I personally don't understand how this pattern of trailing dust can be explained by a collapse mechanism*, but I am interested if anyone can explain these dust trails in accordance with the official collapse story.

*Collapse might cause chunks of columns to separate from the tower like this, but it doesn't explain the thick trailing dust.

1. Jesus, Spooked....

listening to you babble on and on about what you find odd or an anomaly about 9/11, reminds me of that scene from "Rainman" where Tom Cruise is trying to convince Dustin Hoffman that "Who's on First" isn't a riddle. What does it take to convince you?

13. why, Spooked...

what an ugly thing to say. Does this mean we're not friends any more?

[spooked911]

15. we have never been "friends"

I don't think calling you a doofus is particularly ugly. In fact, it is one of the nicer things I could say about you.

[SDuderstadt]

17. Poor Spooked....

no one buying your fucking goofy claims lately?

P.S. Next time I'll be sure to add one of those little sarcasm thingies. I thought for sure you'd recognize that as the line uttered by Val Kilmer as Doc Holliday in "Tombstone". As I recall, he addressed it to someone he really wasn't friends with, either.

2. And why wouldn't the energy from a collapse

also disintegrate all that material too? We know the KE of the WTC was the equivalent of many tons of explosives - energy is energy.

[spooked911]

6. not my point

though there is a different argument to be made about how efficiently the potential energy of the WTC could be used to pulverize interior contents. I have looked at Bazant's calculations for this and found they were seriously flawed.

[Realityhack]

9. "...and found they were seriously flawed."

Can you back that up?
Going to have a paper on the topic published in a peer reviewed journal?

[SDuderstadt]

12. No, it will be on his...

blog. You know, the one he "NEVER directs people to from here" (which is blatantly untrue)?

[spooked911]

22. That's not necessary to see that he's wrong

In terms of a scientific paper, I don't think I could publish a paper that simply refuted Bazant.

I would have to put together a comprehensive paper on the WTC destruction.

And I simply don't have the free time to put that together.

[SDuderstadt]

23. Or, more likely...

you don't have the facts to put a detailed paper together, Spooked.

[AZCat]

24. But you said you'd "looked at Bazant's calculations..."

Surely if you found them to be flawed you could demonstrate how they were flawed.

3. "thick dust."

How do you know how "thick" it is?

[spooked911]

7. the way it forms complex patterns and is clearly opaque

though that's not my major point at all

[LARED]

10. But It is a rather important point

as it takes only a very small amount (ie mass) of dust to appear opaque. What you believe is "thick dust" may in fact be far less material than you imagine.

4. I don't know how dust streams are made...

Regardless, it appears to me as though a solid "chunk" of debris has fallen through a "cloud" of dust leaving the seen pattern behind. Thats just a guess though, I think it is probably impossible to tell what forms a given dust formation from one frozen instant. I think if it were an explosive force, it would be going out at much more of a horizontal angle and not as downward as seen in this photo. Explosions blow debris out and not downward, gravity does that... as in a collapse. Doesn't look like any explosion I've ever seen.

[spooked911]

8. thanks-- at least you gave some thought to it

I agree that it doesn't look like any other explosion I've ever seen, but neither does it look like a gravity-driven collapse with that thick dust spurting out in jets like that.

[vincent_vega_lives]

11. Jets

Jets of air as the volume of the floorspace goes from thousands of cubic yards to zero in a fraction of a second. The dust itself is caused by the crushing of massive quatities of floor concrete and wall board.

Not sure why you can't get your head around this.

[spooked911]

14. I understand the dust creation mechanism

what I find odd is the way all the dust trails, sometimes in dramatic fashion, from the outer columns-- rather than being independent of the outer column sections.

[vincent_vega_lives]

19. Not sure why that is significant to you.

Gravity acts on all debris at the same velocity.

[spooked911]

20. wouldn't dust be more rapidly propelled than the columns by a collapse?

thus wouldn't the dust precede the columns?

[AZCat]

21. Why in the world would the dust "be more rapidly propelled"? n/t

[jberryhill]

26. No.

[Theobald]

25. Why are they dust trails?

Are you suggesting that the dust in the picture is coming from the pieces of building like a tail on a comet? Why? Wouldn't it be more sensible that the dust was created by the pulverization of the building and that it looks like dust trails because the building sections have a greater mass and therefor have a greater free fall velocity? i.e. the building pieces are passing the dust clouds expelled by the collapsing building.

16. 'Thick dust spurting out in jets'

are commonly produced by explosions.






an acknowledged explosion






north tower exploding

18. The problem is

if you watch the video of the collapse, it is not at all like the explosion. The the top plumes are being sucked downward, not being expelled upward as in the explosion. WATCH THE VIDEO.
