Good point Architect.One thing the CTers overlook is that all the hijackers trained in street combat,where almost anything can be a weapon.
Dylan Jones of Loose Change laughed about it,I'd like to see anyone fend off an attack when they're strapped into a chair & the attackers have the dual advantages of speed & suprise.
I know a little about fighting & my main weapon in my last few "incidents" have been those.
