type-rated (757) terrorists ?
Well, it seems from the passengers (who called on the cellulars) that the pilots where whisked away from the cockpit and the terrorists took control of the variouys planes, which are of only two types apparently, 757, 767.
This is disturbing, they probably had training with an experienced 757 or 767 pilot or instructor (middle-east operator ?).
This operation was well put-up and they did have few time to take control until point of impact. When you put someone without exp in a simulator, he does not fare too well.
