Comment: At this point I really don't

At this point I really don't want to watch another whole documentary that I am sure is going to be over half repeated information. It starts out very similar to many I have seen. It shouldn't be surprising to anyone that you could find different accounts of what kind of plane it was and what it looked like to eye witnesses. Every crime or incident that ever happens around alot of people has many different accounts of the specific details from eye witnesses. They always seem to leave out all the people who did see a commercial plane or a United airlines plane though.

Could you tell me what is different about this documentary than the rest? What evidence does it provide that the others don't?
