DCT KJFK/KDCA and then take it visually from when you get close to Manhatten/DC.
The visual part is the tricky bit. The NY aircraft didn't have a problem spotting the twin towers. The aircraft that hit the Pentagon is thought to have had the Whitehouse as it's primary target. It circled DC for a while before going for the Pentagon. It's assumed the hijackers couldn't see the primary and went for the much more obvious Pentagon instead. It's also assumed the fourth aircraft had the Capital building as it's target.
