Just when did the hijacker(s) of Flight 11 reach the cockpit?

[Martin White]

Thanks Peter. I have always been suspicious that Flight 77 was not controlled by a human - well certainly not the alleged hijacker anyway - and I remain unconvinced that it ever even hit the Pentagon.

It is utterly inconceivable that no trace of the four flight recorders were found at GZ. It would have been more plausible to have said "we found them but they were burnt/damaged beyond use".
