"I've carried pliers and assorted screwdrivers on airplanes numerous times in the past couple of years. My favorite screwdriver I carry is a 14" long #2 phillips./Joel in Keller, TX (DFW area)" Since 9/11?? Not through any airport that I've gone through!! Checked, yes - on the plane, no. A small eyeglass screwdriver is the largest screwdriver allowed on a plane. Steve Oxford/'63 conv
