<p>This is a rocket sled fitted with an SR-71 ejection seat. Tests took place at Holloman AFB, NM in 1977.
Only “Enterprise” and “Columbia” were ever fitted with ejection seats, as they were designed for a two-man crew. Later shuttles were built for larger crews and were not fitted with seats. By “Columbia”s third mission, it had been modified and no longer had the seats.
The long retired test vehicle is now on display at the Joe Davies Heritage Airpark,
Palmdale, CA, USA.
