Conde Nast Traveler magazine has posted a lengthy but all-too-speculative piece on the gun-in-the-cockpit situation, which I've been trying to rebut. (I'm also a Conde Nast Traveler writer.) Anybody who wants to join in, go to
www.perrinpost.com and scroll down a short way and you'll find it. The writer, Guy Martin, seems to know just enough about lightplanes to be dangerous...I have a fair amount of business-jet time, at least, and a CE500 type rating.
