Passengers told federal investigators that Abdulmutallab went to the bathroom for about 20 minutes. When he returned to his seat, he said he had an upset stomach and pulled a blanket over him. Passengers then heard a popping noise, similar to a firecracker. They smelled an odor and some passengers saw Abdulmutallab's pant leg and the wall of the airplane on fire.

Here is what I don't get: Why did he return to his seat instead of trying to ignite the explosive in the bathroom, where no one would be able to stop him? And why didn't Richard Reid try to light his shoe bomb in the bathroom where no one could stop him? It doesn't make any sense.
