M2-F3 on lakebed

The M2-F3 Lifting Body is seen here on the lakebed at the NASA Flight Research Center (FRC--later the Dryden Flight Research Center), Edwards, California.
After a three-year-long redesign and rebuilding effort, the M2-F3 was ready to fly. The May 1967 crash of the M2-F2 had damaged both the external skin and the internal structure of the lifting body. At first, it seemed that the vehicle had been irreparably damaged, but the original manufacturer, Northrop, did the repair work and returned the redesigned M2-F3 with a center fin for stability to the FRC.
