Yellowbelly,
Pinal Air Park is indeed Evergreen's heavy maintenance base, and it's a big maintenance facility. They also store a lot of aircraft there, such as the 747 that carries the space shuttles, when it's not in use, and they crew the plane. It's really not that "spooky" a place, actually. I've spent many happy weeks there at our law enforcement refresher training. The Saudis built several firing ranges there, and gave them to Evergreen after they were done training the royal guards. It's actually a fun place, but they aren't too interested in having strangers walk around. That said, there's been an active skydiving school operating out of there for a number of years, and there's an Air Guard unit operating there as well. I got tours of almost all the WWII airplanes that Evergreen now has at McMinville, as they were being rebuilt at Pinal. The fellow who ran their maintenance side there was very friendly and would take us for tours of the planes after work in the evenings.
Tadpole,
Actually, "Tweet Complete" the last official flights of the T-37 took place last fall, I believe. They were still in operation to some degree till then.

Nope, the FAA never had a problem with the Starship, once it was flying. They drug out the certification process massively, because it was the first fully composite turbine aircraft, and FAA didn't have any experience with that material in primary structures. Beech basically paved the way for the whole industry by certifying that airplane. I suspect that the airworthiness certificate is still valid, so he doesn't have to operate it in the restricted or experimental category.
