>>Now why in the world would you blow them up over the atlantic when the only thing below you is water?? <<
From what I understand, the informant who foiled the plot said that they were going to blow them up over the ocean, so that the method used (liquids diguised as sports drinks) could not be discovered.
Well then.... that is thinking ahead.
Hmmmmm.....
Not a bunch of dumb bunnies then.
