Planes unusually empty

The unusual emptiness of the hijacked flights may indicate some attempt to minimize the loss of life, which clearly would not have been a concern of real terrorists but might conceivably have been a concern of US agents orchestrating the attack.

This came at a time when many airlines were trying to save money by overbooking and canceling flights that were not full.
