> The second question is whether the TSA's more onerous policies, like use of full-body scanners and bans on liquids, prevent fatal bombings of airliners (not hijackings). The thing most people don't know is that the reaction of Acetone and Hydrogen Peroxide produces nothing but heat. If mixed in the bathroom out of the smell of anybody, it can be left in a bottle and looking like pure water. It will slowly crystallize acetone peroxide as the reaction occurs. Given enough time - like a 7 hour flight - you could have sufficient quantities of highly reactive acetone peroxide crystals that would likely go off at the slightest movement even while still in a liquid. So screw the bathroom, it's under any seat in any backpack. Most people think of the anarchist cookbook method that uses an acid to form it, which works in creating DADP or TATP which are the more stable variants. However they require a lot of ice, and still take a lot of time anyway. Even a water bottle full of the mixture would produce a sizeable amount of explosive (assuming using 30% hydrogen peroxide). The fucked up thing being I can grab a can of acetone and a can of hydrogen peroxide (wood stain remover) at home depot for under $20. The only question is how do you get it in? Boil a bottle of water and you can pop the lid off it without breaking the seal, keep that in boiling water, refill the bottle with what you want, take the lid out and push it back over, when its cooled it looks like new. I've gone to enough concerts to know how to sneak a bottle of rum in. I really wouldn't want to be on the plane when a guy was allowed to mix together two 1L water bottles to make almost a lb of primary explosives that detonate with almost twice the force of TNT.
