I wonder if this tragedy will be used by politicians to rein in the rights of general aviation enthusiasts? Since September 11th, 2001, general aviation has been under an increasing attack in the name of 'security'. A good example was Chicago Mayor Daley's generic use of "security concerns" to close and destroy Chicago's famed Meigs Field. (Daley had wanted the field closed prior to 9/11 and found a convenient excuse in the tragedy.)

I guess it doesn't matter that much more damage can be done with an automobile than a private plane. Likewise, there have already been two devastating attacks using rental trucks, which seem to pose a much more credible threat.
