I was told at one of the big shows(Oshkosh? AOPA? I forget) by reps at
the Udvar-Hazy booth (with the awesome model of the new Smithsonian
A&S museum) that 4 times per year general aviation aircraft will be
permitted to land at Dulles and then taxi back to a parking area
adjacent to the museum.

It opens 12/15 (a Monday), so I'm wondering what the deal is. Sure
would beat traffic to be able to fly in....
