60-6932 accrued 268 flights and 409.9 hours of flying time.
60-6932 was outfitted for operational use.
Between 22 and 28 May 1967, Weeks flew 60-6932 from Nevada, diverted at Wake Island to correct an equipment malfunction and finished the trip to Kadena AFB, Okinawa.
Wednesday, June 5, 1968
NOTE: the official report says June 4, but most other sources say it was June 5
Don Person (one of the first crew chiefs of the SR-71, and among the first group to be assigned to Det-1 at Kadena AFB), was one of the last people to see Jack Weeks alive. He recalls:
Our KC-135Q tanker was inbound from Beale AFB on 5 June. Before landing we were gathered together and notified that upon landing we would see things we probably were not aware of and not to talk about what we would see (otherwise on a "need to know basis"). The tanker landed and spotted in a revetment. Once the large cargo door was opened and steps were in place we departed to the flight ramp. As soon as we were on the ground I heard the sound of J58 engines coming down the taxiway. As 06932 passed the tanker I noticed this was no ordinary SR-71: no RSO canopy, and red numbers [on one side, white tail numbers on the other]. Just seeing the red numbers instead of the SR-71 white was enough to say this was not a Beale SR-71. We watched it taxi to the active runway and departed a short time later. I can remember we all looked at each other in amazement but did not discuss it as previously advised. Rumors soon circulated that this aircraft was missing. SR-71 #974 (which I was crew chief of) was generated for flight and flew the next day. Her mission was to look for the missing aircraft. No such luck. Months later, I found out about the A-12 aircraft and put two and two together. Not until several years ago did I see another A-12; landing at San Diego you can see one in the Balboa Park. Also driving by the battleship Alabama museum in Mobile Bay I also saw what I thought was a SR-71 on display. Again not true, it also is an A-12.
Because no trace of neither 932 nor her pilot, Jack Weeks, was ever found, some have speculated that Weeks “defected to the other side.”

Please excuse the length of this post (or rejoice in it). The Birdwatcher constantly monitored various vital aircraft system functions, as well as equipment functions. If and when established limits and equipment activity were sensed, the Birdwatcher would key and modulate the HF transmitter with a coded signal. The coded signal was a multiplexed sample of each monitored item, including the item which triggered the Birdwatcher. Thus, the intended receiver operator could determine which aircraft system or equipment triggered the unit and could monitor the status of all remaining items. There were 40 channels available, though not all were necessarily used. The system was controlled from the cockpit with a control panel shared with the ECM and SIP controls on the righthand console. The Birdwatcher unit utilized the HF transmitter, and was located in the lower right side of the E-Bay, just behind the A-12 cockpit (C-Bay). Items monitored by Birdwatcher included generator fail, transformer fail, altitude low, fuel quantity low, destruct active, fuel flow low, hydraulic pressure low, System "A" and "B" active, "A" and "B" hydraulic pressure low, oxygen pressure low, compressor inlet temperature high, System "B" manual jam on, pitch and yaw acceleration, cockpit pressure low, seat ejected, Code "A" and "B", angle of attack high, fire warning, System "C" and "F" activity, oil pressure low, and EGT [Exhaust Gas Temperature] High Derich on. If the Birdwatcher sensed a system limit or equipment activity, it would key the HF tranmsitter and transmit three short, consecutive half-second bursts, each separated by a five-second quiet period. During each burst, the condition of all monitored items , as well as aircraft identity, was transmitted. Upon transmission, the pilot heard three "chirps" in his headset, and an activity light illuminated on the Birdwatcher control panel. "Code A" and "Code B" switches on the panel could be used to retrigger the Birdwatcher to indicate pilot awareness of Birdwatcher operation. By prearrangement, activation of the "Code A" switch could indicate "pilot aware - no emergency." In that case, "Code B" switch activation might indicate "pilot aware - emergency condition." Having transmitted, the Birdwatcher would not key the HF transmitter again until another system limit was reached or another equipment activity was sensed, or if the original triggering system returned within limits and exceeded them again. On 4 June 1968, Mr. Jack Weeks flew A-12 (#129) on a redeployment preparation and functional check flight due to replacement of the right engine. Taxi and takeoff were uneventful, as evidenced by the reception of the required Birdwatcher "Code A" transmission and the lack of any HF transmissions from the pilot. Refueling, 20 minutes after takeoff, was normal. At tanker disconnect, the A-12 had been airborne 33 minutes. The tanker crew observed the A-12 climbing on course in a normal manner. This was the last visual sighting of the aircraft. No further communications were received until 19 minutes later when a Birdwatcher transmission indicated right engine EGT was in excess of 860 degrees C. Seven seconds later, Birdwatcher indicated the right engine fuel flow was less than 7500 pounds per hour and repeated that EGT exceeded 860. Eight seconds later, Birdwatcher indicated that the A-12 was below 68,500 feet, and repeated the two previous warnings. This was the final transmission. Several attempts were made to contact Weeks via HF-SSB, UHF, and Birdwatcher, but without success. Operation of recording and monitoring facilities at the home base continued until the time that the aircraft's fuel would have been exhausted, but no further transmissions were received. The aircraft was declared missing some 500 nautical miles east of the Phillipines and 600 nautical miles south of Okinawa. The accident report declared that "No wreckage of aircraft number 129 was ever recovered. It is presumed totally destroyed at sea." Peter W. Merlin The X-HUNTERS Aerospace Archeology Team
