I wonder if there's a correlation between tightened security around
Washington DC and the airplane that crashed into the Pentagon.

A correlation doesn't prove reason.

People can play logical soccer with the issue all they want, but the
airspace is closed, any legitimate pilot in America knows the airspace is
closed, it's damned difficult to get lost in the DC area and fighters were
scrambled to either deter or destroy the aircraft.

As it should be. There's no particular reason at this point to let pilots
run amok over Washington DC.
