Douglas C-54 Skymaster

On 29 June 1964, a Douglas HC-54 (serial number 42-72590, of the USAF 57th Air Rescue Squadron) and a Boeing HC-97 (serial number 52-2773, USAF 55th Air Rescue Squadron) were involved in an aerial photography mission near Kindley Air Base, Bermuda. To support the NASA Gemini program, it was necessary to train pararescue personnel in the delivery and installation of flotation collars on the Gemini' space capsule. This required placing personnel performing temporary duty at Bermuda where water jumps were to be conducted. In conjunction with this training, a requirement existed to support preparation of a film concerning the "pararescue" mission. Since the two requirements appeared compatible, they were combined into one mission. The HC-97 took off at 11:05 local time, and the HC-54 took off at 11:10. The weather was 2,000 feet scattered clouds, 2,500 feet scattered clouds, visibility 9 miles, and winds variable at 8 knots. Both aircraft arrived in the drop area and because of the clouds, decided to fly the mission at 1,700 feet (below the clouds). Aboard each aircraft were, photographers and pararescuemen. There were also photographers aboard the boats in the drop area to photograph the drop from the surface. As they had briefed before the flight the aircraft established themselves in proper positions. The first run had the HC-97 taking photos as the HC-54 (which was slightly forward and below) began deploying the pararescuemen. Right-hand patterns were flown, and photos were to be shot with the sun behind the cameras, and at an angle that would not reveal any of the land surface in the photos. After a few passes over the drop area with the pararescuemen being deployed from the HC-54, the aircraft changed positions. This placed the HC-54 slightly ahead and below and to the left of the HC-97. After flying one dry run and again in the right-hand pattern, two pararescuemen deployed from the HC-97. Seconds later, the two aircraft collided. The HC-54D suddenly banked to the right, colliding with the HC-97G, hitting the wing or midsection of the HC-97G and sheering both its wing and the tail section, and both aircraft immediately plunged towards the water. The three boats in the area immediately began a search for any survivors. Both aircraft were destroyed, and there were no survivors.

Shortly after takeoff from Río Gallegos Airport, the four engine aircraft encountered difficulties to gain height. The captain decided to attempt an emergency landing in a snow covered field. Both engines number three and four were partially sheared off and three passengers were slightly injured. The aircraft was considered as damaged beyond repair.

Crashed in unknown circumstances some 160 km southeast of Trinidad. There were no injuries but the aircraft was damaged beyond repair.

While approaching Lima-Callao Airport by night, the crew encountered poor visibility due to foggy conditions. The four engine aircraft was too low and struck a sand dune located 15 km short of runway threshold. Two children and a crew member survived while 46 other occupants were killed. The flight was operated by the Argentinian Air Force on behalf of the Correo Aéreo Militar al Exterior (CAME).

The DC-4 took off from Honolulu at 22:47 PST for a flight to Los Angeles, ETA 10:27 PST. At 05:54 PST the pilot reported a bad fire in the no. 2 engine and stated that a ditching might become necessary. Nothing more was heard from the flight. Extensive search efforts were discontinued after 5 days; nothing had been found. A total of 15-17 min maintenance delay had occurred on the Los Angeles-Philippines round trip. Among the causes of these delays was a recurring oil leak in the propeller governor assembly for the no. 2 engine.

The aircraft was on a non-scheduled international cargo flight from Beirut, Lebanon to Kabul, Afghanistan via Kuwait, carrying a crew of three. The trip to Kuwait was uneventful, and it arrived there at 0036 hours GMT on 12 December. Departure from Kuwait for Kabul was at 0256 hours and the flight reported passing Kandahar at 0838 and Kalat at 0900 flying at flight level 110. While en route the aircraft was provided with the Kandahar and Kabul weather. At 0942 hours it reported passing Ghazni at 0940, flying at flight level 150 and estimated its arrival time at Kabul as 10 10 hours. However, at 0958 (i. e. 12 minutes before ETA) it reported overhead Kabul and requested the latest weather situation which was provided. As the aircraft could not land at Kabul because of the weather conditions it reported at 0959 hours that it was diverting to Lahore. Shortly thereafter it reported it was proceeding to Zahedan via Ghazni (ETA 1025), Kandahar (ETA 1130) Zahedan (ETA 13 15). It would maintain flight level 150 to Ghazni, 130 to Kandahar and 110 to Zahedan. At 1003 hours the Kabul tower passed the Kandahar weather to the flight and 5 minutes later the flight reported it was 25 miles out from Kabul, at flight level 150. The aircraft was then cleared by Kabul tower to route frequency and nothing further was heard from it. The wreckage of the aircraft was first sighted on 16 August 1964, after the snow had melted, at an elevation of 13 940 ft amsl in the Koh-i-Safid Mountains 50 NM west of Ghazni and 42 NM from the approved air route. The coordinates of the accident site were estimated to be 33° 37' N 67° 35' E. The time of the accident was some time after 1015 hours GMT on 12 December 1963. The wreckage was found by Afghan soldiers on 16 August 1964.

While on a cargo flight, the crew encountered engine problems and decided to ditch the aircraft 15 km south of Cockburn Harbour, Turks and Caicos Islands. Both crew members were evacuated safely while the aircraft sank and was lost.

While approaching Las Palmas by night, the four engine aircraft crashed into the sea and came to rest 15 km from the runway threshold. The floating aircraft was found in the next morning and 11 occupants were evacuated safely while three passengers drowned. Few hours later, the airplane sank and was lost.

The airplane was completing a flight from Luanda to Lisbon with an intermediate stop at São Tomé. After takeoff, while climbing in heavy rain falls, the airplane stalled and crashed few km from the airfield. All four crew members and 19 passengers (all civilians) were killed while 14 other occupants were injured. It is believed the aircraft was overloaded at the time of the accident.

The crew departed Bogotá-El Dorado Airport in the evening for a night training mission. En route, the four engine aircraft struck the slope of Mt Guayatama located near Suárez, about 100 km southwest of its departure point. The aircraft was destroyed and all five crew members were killed.
