Would one expect GA schools to act responsibly and admit their failure to
provide adequate security previous to 9/11?

Come on, Sky-buffoon... Who could have ever imagined airliners being
used in such an insidious and evil way before 9/11? I suppose given
your known stance on GA this comment really shouldn't surprise anybody
(odd, in light of your admission to resume fight training at some
point, maybe). Feel free to find a new forum to rant and spew your
slanted nonsense - your postings are like so many mosquitoes buzzing
around my ear...

I suspect anybody with a (then) current copy of MS Flight Sim could
have done what the terrorist monkeys did after a few hours flying a 737
around in VR - it ain't rocket science.
