On December 22, 2001, Richard Reid, the "Shoe Bomber", attempted to bring down American Airlines Flight 63 by igniting some Pentaerythritol tetranitrate (PETN) smuggled aboard in the heel of his shoe.

On Christmas Day, 2009, Umar Farouk AbdulMutallab, the "Crotch Bomber", attempted to bring down Northwest flight 253 from Amsterdam to Detroit by igniting some Pentaerythritol tetranitrate (PETN) smuggled aboard in his nasty ass underwear.
