Exposed : Why Nigerian Suicide bomber Abdulmutallab's plan to blow up plane failed

Remember him? On 25th December 2009, Nigerian Umar Farouk Abdulmutallab's plans to blow up a US bound plane  failed after his under pants caught fire...The nearly 300 passengers on board pounced on him and handed him to authorities.

The 27 year old was sentenced to life without parole in February 2012 after pleading guilty to all charges.The head of the Transportation Security Administration said this week the bomb failed to detonate because of how long Abdulmutallab had been wearing his underwear.

John Pistole told the Aspen Security Forum:

 'The bomber had had the device with him for over two weeks.Let's say it was degraded.' 

During his trial, Abdulmutallab said the bomb in his underwear was a 'blessed weapon' to avenge poorly treated Muslims around the world
