Details continue to trickle in about 23 year old Nigerian Umar Farouk Abdulmutallab’s would-be attack on a Detroit-bound airplane, Northwest Flight 253 from Amsterdam. Abdulmutallab apparently kept the small explosive device on his lap, and detonated it from there while sitting in his seat. Passengers say “it sounded like a firecracker in a pillowcase,” and yesterday officials said Abdulmutallab’s injuries were consistent with a firecracker size explosion. Officials now say the device may have been a condom containing a small amount of PETN. AWIP: Suspected plane bomber was in U.S. intelligence reports as having KNOWN ties to "al-Qaida" [CIA].
