61-7965
965 was lost on October 25, 1967. During a night flight, the aircraft's inertial navigation system failed. As a result, her crew was unaware that she had entered a dive. When they realized what had happpened, they were beyond the point of being able to pull up in time. Pilot Maj. Roy St.Martin and RSO Capt. John Carnochan ejected safely. The aircraft crashed near Lovelock, Nevada.

SR-71 serial number 61-7965, call sign ASPEN 28, departed Beale AFB at 0058Z on 25 October 1967 for a three hour night training flight. Papa Route consisted of a high-altitude, supersonic leg to BUSY PALACE air refueling area near Albuquerque followed by a second climbing acceleration east of Denver and return to Beale on a westbound leg north of Salt Lake City. The flight progressed normally through the air refueling and second acceleration to supersonic cruise. Descent and deceleration from cruise was initiated in the vicinity of Elko, Nevada, approximately two hours and fifteen minutes after takeoff. After completion of checklist item "Throttles - retard and set 6300 to 6100 RPM" in the Mach 2.0 checklist, the pilot observed a warning flag on the bank steering bar of the attitude director indicator (ADI). At this time the pilot also observed that the autopilot had become disconnected. The ADI showed wings level flight and the horizontal situation indicator (HSI) showed straight, non-turning flight. Because of the warning flag on the ADI steering bar, the pilot switched the attitude reference source to the Flight Reference System (FRS). The ADI showed an immediate unusual attitude of undetermined magnitude, and both the warning flag on the stering bar and the OFF flag on the ADI appeared simultaneously. The pilot advised the RSO that he had attitude indicator malfunctions and the RSO confirmed that his astro- inertial/navigation system (ANS) had stopped functioning as a valid reference source. The RSO, on FRS, observed his attitude indicator reflecting a large left wing low, diving turn. Due to the radical attitude displayed in FRS, he stated to the pilot that the FRS was inoperative. However, there were no OFF flags on the RSO's attitude indicator. The RSO switched to ANS and it showed wings level, constant heading. The crew was not aware that the aircraft was making a 180-degree turn towards the east as observed by Oakland Center. The speed had increased to 480 KEAS where the pilot felt that he had stopped the trend of increasing airspeed. The pilot had no outside reference to assist him in the recovery from the unusual attitude because of the darkness. Recovery could not be effected using the standby attitude indicator. The pilot directed the RSO to bailout, passing an estimated 30,000 feet. The pilot remained with the aircraft for an unknown duration, continuing his efforts to recover, but was unsuccessful. He ejected from the aircraft at an unknown altitude and speed. Both crew members had successful ejections. The aircraft struck the ground in a near vertical dive and was totally destroyed upon impact. The crash occurred at 0320Z in an isolated area with no witnesses at or near the scene of the accident. Total flight time was approximately two hours and twenty minutes. |
