I was just watching the documentary 'Conspiracy Files 9/11' on youtube (http://www.youtube.com/watch?v=Ylwz3EqpgcU) and noticed what sounded like an interesting slip of the tongue 21 minutes into the piece (21:31 to be precise). One of the pentagon rescue workers is refuting the 'no debris' claim and is describing what he saw that day.

Please listen to it and tell me that i'm not the only one that thinks he realises halfway into the word that he's saying too much and tries to skip over it.
