This is a nice step forward, congrats.
The witness who is actually right, but this is a little different. If you could find a single witness who saw a missile, you could - I suppose - use his testimony in favor of the missile theory in a court. But the problem here is that everyone who saw the projectile that hit the Pentagon identified it as a large airplane, some even correctly identified the airline(AA) and model(757) and one incorrectly identified it as a 737.
When you add the DNA matches to all the passengers, 757 specific parts(like struts, turbine sections, tires and wheels) and a flight 77 that never landed...theres only one logical conclusion - it impacted the Pentagon.
