Those pictures were obviously taken sevral years ago, before the SR-71s departed NASA Dryden Flight Research Center (DFRC) for permanent museum
The upper picture shows three D-21B drones. Following the D-21/M-21 accident, all remaining D-21s were converted to D-21B configuration for launch
from a B-52H. Those D-21Bs that were not expended in test or operational missions were placed in storage at Davis-Monthan AFB, Arizona.
On 1 June 1994, two D-21B drones (articles 525 and 529) were delivered to NASA Dryden inside a C-17A (USAF serial no. 89-1189) from the Aircraft
Maintenance and Regeneration Center (AMARC) at Davis-Monthan. The next day, two more drones (articles 513 and 537) were delivered to Dryden inside the
same C-17A. The total cost of the delivery service for all four drones was $1.00.
513, 529, and 537 were later borrowed by Northrop-Grumman and then returned to DFRC in 1998. They are currently in storage on the edge of the lakebed
near the Space Shuttle area. 525 was loaned to Blackbird Airpark in Palmdale, California on 14 October 1994.
