Lockheed C-141 Starlifter

The crew was completing a local training mission at Charleston Airport. Upon landing, the crew noticed the lack of a 'brakes released' light. After touchdown, thrust reversers failed to deploy because they were locked out by the touchdown relay, still in the Flight Mode. However, due to a malfunction, the n°4 thrust reverser did deploy. Normal brakes were inoperative. The copilot selected emergency brakes and then continued to make multiple attempts to deploy the spoilers. This caused the n°3 hydraulic system to lose pressure due to which in turn the emergency brakes failed. Then an electrical malfunction within the gear handle caused the nose gear to retract. The airplane came to rest in flames on its belly. All six crew members escaped with minor injuries while the aircraft was damaged beyond repair.

The Starlifter registered 67-0006 had a recent history of weather radar problems. It had been written up by crew members eight times previously. On the day of the accident the maintenance crewman, unaware of the previous problems, checked the radar. It seemed to be working, so it was signed off as "Ops Check Okay". Shortly after takeoff from McGuire AFB, the crew noticed that the radar was inoperative. Since severe weather was not forecast, they elected to continue to RAF Mildenhall, UK. Two hours after takeoff, British forecasters issued a SIGMET for "Moderate to occasional severe clear air turbulence from FL240 to FL400", but the crew never got this report. Four hours after takeoff the crew updates the weather forecast. They receive a weather forecast of "3/8 at 3000 feet, 4/8 at 4000 feet with an intermittent condition of wind 030/12 gusting 22, visibility five miles in thunderstorms, 2/8 at 2000 feet 5/8 at 2500 feet". The crew then attempted to get an update one hour from Mildenhall, but was unable to contact the base. Another station reported "4/8 Thunderstorms tops to FL260". During the enroute decent they entered the clouds. At FL150, they requested vectors around the weather. Because the primary radar was inoperative, the controller advised that he would have difficulty providing avoidance vectors. The aircraft then entered the leading edge of a very strong line of thunderstorm cells. One estimate indicated they encountered a 100 mph downward vertical airshaft. The right wing had failed, followed quickly by the upper half of the vertical stabilizer, and the four engines.

The aircraft departed Thule Air Base on Greenland for a two-hour flight to Sonderstromfjord Air Base. From Sonderstromfjord it was to return to Thule and continue back home to McGuire AFB. The flight carried enough fuel for the flight to McGuire. Following a PAR approach the airplane landed slightly long on the 9235 feet long runway 11. The aircraft rolled for 1,500 to 2,000 feet with no thrust reverse or spoiler deployment. A go around was commenced. The plane then rotated abruptly and lifted off the runway with a pitch attitude as high as 45°. The aircraft stalled. The left wing struck the ground and burst into flames. The aircraft became airborne again with portions of the left wing missing. It flew for 650 feet before striking the ground with the right wing, causing it to catch fire. It then bounced once more and disintegrated 500 feet from runway centerline.

The airplane was conducting a flight from Clark AFB, Philippines, to McChord AFB with intermediate stops at Kadena AFB, Okinawa, and Yokota AFB, Tokyo, carrying 16 people among them six marines. En route to McChord, while cruising by night, the crew established contact with ATC and was cleared to descend from FL370 to FL150 then FL100. Few minutes later, after confusing the C-141 with another Navy aircraft, the air traffic controller cleared the crew to descent to 5,000 feet which was a too low altitude for the area. While descending at an altitude of 7,000 feet in limited visibility, the four engine airplane struck the slope of Mt Constance (7,756 feet high) located in the Olympic National Park, about 52 miles northwest of McChord AFB. The airplane impacted the mountain about 150 feet below the summit and caused an avalanche. Debris were found scattered on a wide area and none of the 16 occupants survived the crash.

The crew was completing a flight from Howard AFN, Panama, to La Paz. While descending to La Paz-El Alto Airport, the crew encountered poor weather conditions with limited visibility due to clouds from 700 to 24,000 feet. The crew informed ATC about his position about three minutes from La Paz VOR when he was cleared to descend from 24,000 to 18,000 feet. Shortly later, while flying at an altitude of 18,700 feet, the airplane struck the slope of a mountain (20,000 feet high) located 28 km north of El Alto Airport. The airplane disintegrated on impact and all seven crew members were killed.

The C-141 departed Athens for a night-time flight to Madrid, the first leg of a flight back to McGuire AFB. The crew were cleared for an ILS approach to Torrejon's runway 23. Weather was reported as 20,000 foot overcast, with 10 NM visibility. During the descent the crew forgot to use the Descent Checklist. Thus, the crew had failed to set their altimeters from 29.92" to the local altimeter setting of 30.17". Additionally, they did not turn on the radar altimeter. While at FL60 the crew was given a clearance to a lower altitude. Because of heavy radio traffic, the clearance was garbled. They were not sure if the controller had cleared them down to 5000 or 3000 feet. They agreed that it must have been 3000 feet. They read back "three thousand feet", but the controller failed to notice the error. When reporting "passing 5000 for 3000" to another controller, the error again was not noticed. Nearing 3000 feet, the navigator noticed a hill ahead and above their altitude, but the pilot reassured him that "everything looks clear ahead", with the lights of the air base visible in the valley below. At an altitude of 3050 feet, at a speed of 250 kts, the airplane impacted terrain near the edge of a plateau, 40 km east of the Torrejón Air Force Base. It became airborne again, rolled over and disintegrated in a field. The navigator survived while 24 other occupants were killed.

While taxiing to the runway for takeoff the crew completed the Before Takeoff Checklist. The copilot inadvertently missed the item referring to the automatic Spoiler Select Switch. The switch should have been in the "Rejected Takeoff" (RTO) position, but was in the "Autoland" position when the airplane departed. Unnoticed by the crew, between 34-60 Knots, the spoilers automatically deployed to the ground position. The crew noticed a reduced acceleration rate, but elected to continue the takeoff. The aircraft became airborne, accelerated poorly and began a shallow descent. It crashed into the sea just off the end of the runway. Six crew members were killed while two others were rescued.
Those killed were:
Maj Harry Milton Brenn,
Cpt Morris Bowdoin Witt,
SMS Roy Earl Shults,
M/Sgt Herman Eugene Miller,

Some of the bases in South Vietnam were among the world's busiest airfields during the height of the war in Southeast Asia. The number of aircraft movements at bases like Đà Nẵng and Saigon-Tan Son Nhat Airport equalled or exceeded those at major US and European airports. With the huge amount of activity involved it is inevitable that accidents should sometimes occur on the ground. The worst such accident happened in the early hours of 23 March and involved a Marine Corps A-6, which was taking off from Đà Nẵng on a strike mission, and a MAC C-141 Starlifter. The air traffic controller had cleared the Intruder to take off but also unwittingly cleared the C-141 to cross the runway. The Intruder pilot saw the Starlifter at the last moment and tried to veer off the runway to avoid it but the Intruder's port wing sliced through the Starlifter's nose. The Intruder sumersalted onto its back and continued down the runway. The pilot and navigator miraculously escaped death and crawled through their smashed canopy. The aircraft was carrying 16x500lbs bombs and six rocket packs, some of which later exploded in the fire. The C-141 immediately burst into flames igniting its cargo of 72 acetylene gas cylinders, which resulted in a tremendous explosion. All the Starlifter crew died except the loadmaster who managed to escape from one of the aft doors before the aircraft exploded. The identity of the crewmen who survived remains unknown.

On 7 September, 1966, 65-0281 was the first C-141 destroyed. It blew up while simultaneous hazardous maintenance procedures were being performed. Three maintenance members were killed in an explosion of the Right Extended Range tank. The Wing at McChord had recently converted to the StarLifter. The first aircraft had arrived on 9 August 1966. This aircraft, 65-0281, was the third C-141 to be stationed at McChord, and had arrived on base just a week before, on 29 August, 1966. The maintenance teams had minimal practical experience with the new airplane. It was having multiple maintenance difficulties. The Right Extended Range Tank feel gage was erratic, and the AC "Power On" Light was inop. Two electricians were in the cockpit working on the "Power On" Light. A Maintenance Team Chief was also in the cockpit with three trainees. In addition, he was supervising a maintenance team on another aircraft. The Assistant Team Chief had started de-fueling the Right Extended Range Tank to prepare it for troubleshooting. The other fuel tanks were full. Two additional technicians arrived to work on the fuel gage before the de-fueling was complete. One of the electrical technicians connected testing equipment to the fuel tank but failed to ground it. The other technician plugged an extension cord into the external 115V AC receptacle of the APU. The live extension cord apparently came in contact with the case of the test equipment. Electricity flowed through the case, up the cables into the tank. Due to a short in the coaxial shielding a spark was created within the nearly empty tank. The right wing exploded. The Assistant Team Chief standing under the wing, and the technician on the wing were killed almost immediately. One of the technicians in the cockpit was badly burned while exiting the right troop door into a burning pool of JP-4. He died a few days later. The others on the aircraft received only minor injuries.
