What I'd really like to see is Microsoft putting a link to Google Earth (or, more likely, Windows Live), in Flight Simulator, so you'd see the "real" scenery when you fly rather than the artificial terrain and scenery textures. That would probably be enough to keep me from leaving the house for a few days.
If you're having trouble getting it to work, try zooming in on an airport and then hitting crtl-alt-A again. I couldn't get it to work until I zoomed in on DCA.
Classy of them to include Meigs as one of the few options.
If you want to use an airport other than the few in the list, you can zoom in on the runway you want in the regular mode, tilt the view until you're looking at the horizon, then start the flight simulator and use the "current view" option.
