A bomb, that's what.
To get his bomb into this room, Abdullah Asieri, one of Saudi Arabia's most wanted men, avoided detection by two sets of airport security including metal detectors and palace security. He spent 30 hours in the close company of the prince's own secret service agents—all without anyone suspecting a thing.
How did he do it?
Taking a trick from the narcotics trade—which has long smuggled drugs in body cavities—Asieri had a pound of high explosives, plus a detonator inserted in his rectum.
The ass bomb was detonated remotely by text message. The Al Qaeda ass bomber's intended target—a Saudi Prince (wouldn't it be great if Al Qaeda only targeted Saudi princes?)—survived the attack, the ass bomber did not. But before you laugh it off:
"This is the nightmare scenario," said Chris Yates, an aviation security consultant. On a plane at altitude, the effects of such a bomb could be catastrophic. And there is no current security system that could stop it. "Absolutely nothing other than to require people to strip naked at the airport," said Yates.
And al Qaeda says it will share its new technique via the Internet very soon. There is nothing that can stop that either.
After the shoe bomber's attempt—a very nearly successful attempt—to bring down a plane over the Atlantic, we all had to start taking our shoes off at security and passing them through the metal detectors. What on earth are they going to do to us after an ass bomber brings down a passenger plane?
