A minute ago you were saying unique IDs weren't on parts, now you're saying they are. All I'm saying (since you obviously missed it) is that a motivated terror group could orchestrate an aircraft theft like this by tossing some ELTs (programmed to match the target aircraft's ID - maybe even the actual ones FROM that aircraft) into the sea along with whatever other debris (or even bodies / parts) as "proof" the aircraft crashed, then wait a couple of months and then use the still-perfectly-functional aircraft for whatever nefarious purpose they've got in mind... Maybe it's a bit Tom Clancy-ish but if I could think of it, I'm sure the bad guys could too.

I'm not saying at all it'll happen, but it could. I'm sure your type would've dismissed the whole "hijack airplanes and use them as weapons" tactic as a nutty manifestation of paranoia too -up until about September 10, 2001.

There are an awful lot of crazy people in the world with vendettas, political agendas and scores to settle. Never underestimate how resourceful a truly motivated, crazy enemy can get.
