well, allow me to clarify. being the father of one of the pilots' surviving spouses, he was intimately aware of the details of the investigations. suffice it to say that the conclusion come to was that the crew was overtaken by violence after putting up a fight. I won't be graphic out of respect for the surviving loved ones.
Perhaps the title refers to the passengers...
The Tower flights were shorter, and the poor folks on them had less time to react , etc.
The passengers on #93 had the "advantage" of time, and some extra info, I think..
