Is the risk of an airplane again being used 9/11 style about 100,000 times as high as the risk of a bus being bombed? Because between the pointy object agency and the FAMs and the National Guard at the airport (remember that joke - no mission, no rules of engagement) I assume we are spending about 100,000 times as much (add the lost productivity of air travelers) to protect airplanes as we are to protect busses.

What about if 10 busses were all bombed on the same day. Would that have a psychological impact? Are we spending an equal amount to protect them? If it happens, will people say "My gosh, I didn't know that we let busses operate without police escorts." I want to see the FAM's reassigned from First Class on Delta to 8 hours a day on busses in downtown areas. At least they would have some actual crimes to deal with and they would be protecting people in need, while waiting for the terrorists.
