The addition of the Linear Aerospike SR Experiment (LASRE) pod to NASA's SR-71, tail number 844, added seven tons to the aircraft. This Feb. 15, 1996 photo of the pod's fit-check at the Lockheed Martin Skunkworks in Palmdale, California, shows the LASRE package being hoisted above the aircraft, which has it's right engine pod and the attached wing up. The SR-71's engines, tails, and various other parts are removed for refurbishment.
