This mishap was caused by the MTP’s adverse physiological reaction to high acceleration forces
and subsequent loss of situational awareness (SA) during recovery from the third test maneuver.
The pilot channelized his attention to fight off the effects of high g-forces, characterized by
grayout, light loss, and/or tunnel vision; meanwhile, the aircraft entered an extreme nose down,
high-speed attitude from which safe recovery was not possible. The pilot regained some SA but
determined he was too low and descending too fast for a safe recovery. Lockheed test pilot David P. Cooley he ejected from the aircraft outside the ejection seat design envelope and sustained fatal injury.
