It is a much better sequence

should be:

It is a much better video sequence of the debris

[Dialup Llama]

I wish it had merely travelled under the wing. The debris seemed to initially waver between going over or under, and then went under and took a huge divot out of the wing tiles.

Yep; thanks.

Bump...

Does anybody know what this "insulating foam" is made of? I have ben wondering how hard this material might be.

[South40]

Same thing

Thanks. Good link

Spaceflight Now has had very good coverage thus far

First NASA says it was no big deal. Now they are "focusing" on this as a likely cause....go figure.

YOU ARE A REPORTER. What Question would you ask Sean O'Keefe about the shuttle tragedy-

Thought you might want to see this clip.

Did anyone else notice something I noticed when replaying the clip over and over? The attitude of Columbia distinctly jumps to the right in the frame right after impact (the frame where a spray of disintegrated material appears below the left wing).

If I am right, then the force applied to Columbia by the foam impact must have been significant to shove Columbia over even a couple of feet from its previous trajectory.

Looked more like a large chunk of ice than it did foam as it bounced off the tank first and split into two pieces which struck the left wing near the wheel well area. A 50 pound chunk of ice at Mach 3 would do a lot of damage to the tiles and landing gear door.
