A plane comes in for landing at Washington National Airport. This picture (and the one at right) was taken from Gravelly Point park, along the Mt. Vernon Trail. These aren't great pics; perhaps I'll try again for something more like this the next time I'm there.

Watching planes take off and land here makes it very clear why some people considered closing National Airport permanently after September 11, 2001—the normal landing route of the planes takes them basically seconds from impact with lots of possible terrorist "targets" in D.C. and Virginia. But that's probably true of lots of city airports, isn't it?
