Personally I find it hard to believe that they would use commercial flights to carry such a device. Why risk that when they can use a small aircraft.

Could do both - simultaneously. Use the big plane like 9/11 and the smaller plane(s) for bio or rad attacks.

I would expect at least an attempt at that...multiple venues...including small town grassroots. Heads up time.
