I would like confirmation on this as well, but to be honest, it really does not sound like an impossibility. It would be much more difficult to do that today, but as we know it happened in the past (the movie "Catch Me if You Can" was a true story...
I'm not saying it isn't true but I just did a google and there is some question about its validity. I always prefer a direct link before I feel comfortable with such postings.
I will say this however. I once lived next door to a TWA captain who flew out of St. Louis. He insisted to me that TWA800 was shot out of the sky and that it was impossible for the official story to be true. He told this to me personally but I really don't agree with him. The evidence suggests otherwise, although I don't want to derail this thread.
There are a lot of questions about Atta that I would dearly love to have answers. The one question I have for anyone is where was Atta between April 4, 2001 and April 11, 2001? I'd like just one person on the planet to come forth and say they observed him, saw his signature or any other defnitive documentation that would place him in the U.S. during that period of time. This goes to the disputed Atta Prague story. I've been accused of a conspiratorialist on this issue but I'm still unsatisfied with the official line that there was no Atta-Prague connection.
