Yes - four planes crashed that day. The question being raised is if the planes listed actually hit the towers (including the one carriny my friend). For the people who claim that different planes were used (in fact, one link claims that listed flights were not even flown that day) still have to answer the one basic question - where is my friend?

He was very knowledgable about airliners since he sold equipment for them. If he was supposed to get on a 757 and it was a 737 he would have know immediately. And since that plane could not fly across country like his ticket said, he would have thrown a fit!

So - if the flights did not fly that day - where is he? If the flights flew that day but were diverted so radio controlled 737 aircraft could be used - where is he? In short his wife and daughter would like to know - where is he?
