I bet this was the biggest cost; you just don't
learn how to fly a big
commercial jet overnight.
In this case though not as big an expense as it normally is
since the hijacker's obviously knew it was a one-way trip so they
didn't have to worry about learning to land and such. Granted, if
you're flying by the book it gets quite involved but to take over a
plane already in the air and keep it in the air wouldn't be that
hard. The navigation would've been the hard part, unless of course
the real aircrew was kept in the seats up until very near the end.
