... notably before 9/11 ...
Derailing the thread, I took my first flight, age 18, in 2001. I was into carrying lots of tools on my belt / in my pockets back then, so carried on a pair of pliers, crescent wrench, flat head and phillips screwdrivers, a Swiss Army knife, a penknife, about six feet of baling wire, and lord knows what else. Dumped it all into the little round change tray, sent it through the X-ray machine, and re-pocketed it on the other side.
Those were the days.
