Trust me, I do not underestimate them one bit. You are right about reaction time, the plan sounds plausible. I still think they would need to subdue the passengers (gas?) to pull it off. As far as the Twin Towers, I bet AQ knew that they had a damn good chance to bring them both down (they believed the truck bomb would do it in 93 – learned from the mistakes and went at it from a different angle). The way the structure was built, it could not stand the fire from those full transcontinental planes. It was an ingenious plan.

Right, I seriously hope those with access to an airplane ventilation system and the food services are being scrutinized very closely.
