It's happened to all of us. You're packing for a trip to visit relatives in Cleveland and your uncle calls to ask if he can borrow your chain saw. "Sure!" you reply. "Let me just gas it up and stuff it in my suitcase!"
On second thought, that's never happened to anyone. Except one apparently insane person passing through the Elmira Corning Regional Airport in New York. In January 2012, TSA agents removed the offending power tool – gas being flammable and all [source: Burns]. Interestingly, it's perfectly kosher to pack a chain saw into your checked luggage as long as it isn't filled with gasoline.
