Its as simple as how "mules" run dop,they feed the Islamoterrorist a bunch of ballons filled with C4 or a high explosive 12 hours before the flight, the detonator is in the rectum, the wires would connect to a voltage source that nowadays can be anything like a car remote, hitech watch, cell phone or an Ipod.
Next they will try concealing the detonater in an obscure item, mark my words.
excuse my typos, I just woke up and busting a gut reading about this!
