Umar Abdulmutallab made headlines late last year. He attempted to detonate a bomb on a Detroit flight. What would have happened had he been successful?

Reporters at the BBC wanted to find out. So, they teamed up with an explosives expert. They found a Boeing 747 fuselage. And they detonated a bomb precisely where Abdulmutallab was sitting. Surprisingly, the plane may have survived the blast.
