HAHAHA, Good one guys, rubber on the bottom), I set mine on the wing of a Chieften during preflight and just as I rotated at about 85 knots I caught it sliding off the left wing onto 27R at OAK---I was impressed that it hung on that long but pissed off all the way to LAX cause I was thirsty!
BACK TO DUCT TAPE---Are you aware that the only reason we had air superiority in Europe during WW II was because Hitlers duct tape factories were primary targets and that just about grounded the entire Luftwaffe (that's a fact because Chuck told me!)
