Our tour of NASA's Dryden Flight Research Center was very extensive.  We saw most of the experimental aircraft that NASA has tested during the 1990s, like the F-16XL and F-15 ACTIVE, as well as many support aircraft and even aircraft being modified for future experiments.  We spent over an hour playing in two simulators; one an F-16 and the other an F-15.  While not full motion, these are very important tools for test pilots and engineers alike.  One of NASA's F-18 chase aircraft is undergoing maintence in the picture below.  More phots will hopefully be available soon.
