On 11/8/82 NASA test pilot Richard E. Gray was on a routine mission from the NASA Dryden facility at Edwards AFB Flight Test Center flying the Cessna T-37B N807NA. Mr. Gary was to perform a series of spin proficiency tests in an area northeast of Edwards AFB. It appears that during the test, the T-37B entered flat spin at an attitude of approximately 19,000 feet MSL that the pilot was unable to recover from. The pilot did eject, but at an attitude to low to allow for chute deployment and was killed on impact with the ground. The aircraft impacted flat and burned.
