Animations of Planes Hitting the Twin Towers
Two animations purport to model flights 11 and 175 crashing into the North and South Towers:
These animations were posted at the website of Engineering News-Record, a subsidiary of McGraw-Hill, back in 2003 (I just saw them yesterday for the first time).
And NIST has made 2 animations of its own:
NIST's animations are linked from this page.
Are these animations accurate, in the sense that they show what Boeings crashing into the Twin Towers would have looked like? If so, does that refute the argument that there should have been more aircraft debris outside of the Twin Towers?
If the animations are not accurate, would discrediting them also help to discredit animations of the purported Pentagon plane crash?
