Holiday travel is always a headache, and the relatively recent threat of terrorism has given fliers one more unlikely but horrifying thing to stress about. Luckily for passengers aboard a Christmas Day 2009 flight from Amsterdam to Detroit, Michigan, when these attacks do happen they aren't always successful.
The would-be attacker's name was Umar Farouk Abdulmutallab, a 23-year-old Nigerian who attempted to detonate a bomb concealed in his underwear as the plane made its approach into Detroit. Passengers reported hearing a noise like a firecracker, which turned out to be the sound of the bomb as it failed to detonate. Abdulmutallab was nevertheless engulfed in a fireball and flames soon spread to the plane's carpet and walls. Fortunately, passengers were able to subdue the man and extinguish the flames, and the plane landed without further incident.
Later investigations determined that Abdulmutallab was radicalized by Yemen-based Islamic cleric Anwar al-Awlaki and sought to carry out the attack in revenge for what he felt was the killing of innocent Muslims by the United States. He remained unrepentant as he faced eight charges, including attempted use of a weapon of mass destruction and conspiracy to commit an act of terrorism. A judge ultimately sentenced him to life in prison. But best of all, the 289 passengers and crew on that harrowing flight were able to return to their families for the holidays [source: Ariosto and Feyerick].
