Very good ideas, all! It occurs to me that like all survival situations, your kit counts only if your kit is on you. I'd attach the kit to you -- maybe the belt -- so when they suck you up into the spaceship with that bright beam, you'll still have it with you!

I'd bet Bear Gryllis would probably try to rappel down the side of the UFO. That sort of stuff is too difficult to pull off, especially in a survival situation when your hindquarters might be hurting.
