Well I feel the two planes that hit the world trade center did not contain any passengers; they were remote;
as far as 93, which landed in Cleveland. They interrogated the people, recording 10 minutes of voice, got their information.
made the fake calls, and plated the fake black box...
then executed them; If you noticed they were the only people who got a "hero" story; they were "heroes" who took down the terrorist.
I think that hero story was made up to honor their names; after being executed.
and the families received money as well.
