This document summarizes and comments on the failed underwear bombing attempt by Umar Farouk Abdulmutallab on Christmas Day 2009. It discusses how the bomb failed to detonate because Abdulmutallab had worn the same underwear for over two weeks, degrading the explosive device. It also notes speculation that his lack of washing hands after spending over 20 minutes in the toilet on the flight may have contributed to the failed attack. The document concludes by questioning if Abdulmutallab's lack of personal hygiene would affect his chances of receiving 72 virgins in paradise as promised by radical Islamic teachings.
