Photo's from Dryden of many of the vehicles in this thread: Be careful of your search spec in Google: several of the photo's of the SR-71/Y-12 drones on other sites were listed as D-12 (and M-12) - rather than the M/D-21 that should be used.
I've been trying to find the drones at AMARC, but I can't quite make them out from the resolution of Google Earth (which just came out for Mac, and I've been compulsively surfing it this weekend). The Google Earth images still have a fair number of intact B-52s, and I think they've all been chopped up and carted off, so I think the pics are a few years old.
AMARC also had a number of Titan II boosters when I was there, decommissioned as ICBMs and mothballed for use as satellite launch vehicles. I think they've completely depleted that stock.
