I watched several videos from eyewitness's, and they all seemed pretty credible to me. I have a friend of mine, who is an airtraffic controller, and was working that day. (he works out of a Cleveland airport) He watched the Pennsylvania plane go down on his screen. And no, there wasn't any air force jets in the air at the time.
Suba, in one of your posts, you said your a pilot. And that dynamics wouldn't permit any jets the size that hit the towers to fly that low. Am I guessing that if air speed was slowed down some, that jets could fly at that altitude for some time?? Just wondering how fast they could be going?? gypsyman
