Commonly referenced as the "underwear bomber" or the "Christmas Day bomber," Umar Farouk Abdulmutallab was sentenced to life in prison last week by U.S. District Judge Nancy Edmunds in a Michigan court. He unexpectedly pleaded guilty on October 12, 2011 (day two of his trial) to eight felony counts, including attempted murder and attempted use of a weapon of mass destruction, related to reported attempt to detonate an explosive hidden in his underwear while aboard Northwest Airlines flight 253 flying from Amsterdam to Detroit on Christmas Day, 2009. There were 279 passengers and 11 crewmembers aboard that flight.
