Why Did the 7/7 London Bombers Leave Behind 16 Bombs?

The London bombers left a stash of 16 unexploded bombs in a car, some packed with nails, it was revealed today.

Security experts believe the July 7 plot, which killed 56 people, may have been planned to be much larger and the explosives intended for a second strike.

The bombs were recovered from a car believed to have been rented by suicide bomber Shehzad Tanweer, according to ABC News.

The vehicle was found five days after the attacks in Luton, where the bombers boarded a train to London.

Need I mention that this really takes the wind out of the idea that the 7/7 bombers were suicide bombers?
