i've been to davis-monthan afb, and getting up-close and personal with an a10 was by far my favorite part.
bad gun handling, i know, but i just had to stick my fingers in the bore of that 30mm!
my tour guide had worked on a10s during desert storm, and had stories of jets that had been shot to heck, but kept flying and made it back.
apparently there is a redundant manual backup for all the hydraulic controls, so even if your hydraulic lines were severed, you could manually (with some effort) keep control.
pretty impressive in design and aesthetics.
love the warthog!
