The Impossibility of Flying Heavy Aircraft Without Training

Immanuel,

Would someone with little or no flight experience
be able to fly a 737, 747, or 757, and also make steep dives and sharp turns?

Irrelevant, since the terrorists were trained. And little training is enough
for the easy flying they did.


Standard Boeing commercial aircraft have locks on the cockpit doors. How
difficult would it be break one down?

Only now they have those.

What are the chances that 8 trained pilots and co-pilots, with military
backgrounds, could be physically overpowered by a few thugs with box-cutters?

It's not a matter of overpowering, it's a matter of airline policy regarding
hijackings before 9/11. That policy was: If someone comes into the cockpit with
a boxcutter held to the throat of a flight attendant, you give in to their
demands. And for the flight attendants, the policy was: If they threaten you,
you give them access to the cockpit.
