From top to bottom the three to the east are:
AV-8C (719)
F-104G (825 N825NA)
U-2 (708)
In front of these three is a HiMAT (Highly Maneuverable Aircraft Technology unmanned experimental vehicle)
The little brown blob in front of the HiMAT is a section of a fan from one of the wind tunnels. It's made of wood and each blade is about four feet thick.
There is also a mock-up of the space shuttle a bit further to the south.
A bit north there are two sections of an Atlas missile.
