I know this stuff is really important to some guys on here who love arguing the nitty-gritty but really......do you actually attach such pure gospel, scout's honour, cross my heart and hope to die, on my mother's grave type fides to the statements from anyone who has been in deeply traumatising circumstances such as happened on 911?
The average person does not consider every word they utter as if it was being said in front of a Grand Jury - they want to tell you what they saw - but end up telling what they like to remember which might not be the same thing.
I like Shakespeare - even if you don't - let me tell you, he has a quotation for every scenario! In Henry V, the King is looking out at the field which will be Agincourt the following day - "yonder flags mark out the distance to the French my liege" says an eager lord. "Who has measured the ground?" asks King Henry. Meaning can those flags be trusted, after all it was dangerous work to plant them under fear of a hail of arrows if you were seen. Luckily for Henry, his guy was brave and competant - this can't be said of everyone even if they don't have political axes to grind.
On the grounds of correctness - I do wish that everyone didn't harp on so much about "explosions" on 911 - there weren't any. An explosion must produce a percussion wave to qualify as one - take a look at video of Fukoshima nuclear plant after the tsunami -

Now, review 911 - did anyone see a wave or waves propagating away from WTC? No? Me neither. All of the noises heard, including the aircraft strikes were merely large bangs and nowhere near proper explosions.
