Circumstances:
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.

Probable cause:
The primary cause of the accident was undetermined, but Air Force investigators concluded that probable cause was an incapacitation of the HC-54 pilot. An autopsy revealed cardiovascular issues which may have caused acute chest pains.

Circumstances:
At 8:15 PM on Monday, June 27, 1960, crew T-51 of the 380th Air Refueling Squadron departed Plattsburgh AFB aboard a KC-97G for the "Fighting Fox" air refueling area over Maine. Their mission was part of a SAC Operational Readiness Inspection of the 380th Bombardment Wing code named "Jet Stream Golf". They, and a backup KC-97G, were to refuel a B-47 under simulated combat conditions. The mission was expected to last just under four hours, with both tankers returning to Plattsburgh. After a successful rendezvous with the bomber, the tanker descended to the refueling altitude of 15,500 feet and accelerated, nose down, to 190 knots. The low altitude, when compared to today's KC-135 and KC-10 operations, was one of the necessities of refueling jet bombers like the B-47 and B-52 with a reciprocating engine powered aircraft. As the B-47 closed with the KC-97 from a higher altitude in "observation" position, everything seemed fine. Logistical radio exchanges were made and the bomber began to descend and close into refueling position. As they approached, the B-47 pilot and copilot saw a long stream of flame come back toward them from the KC-97's number one engine, then suddenly disappear. A small spot of white hot glow was noted near the rear of the number one engine. Seconds later, a large ball of flame enveloped the engine and the surrounding wing area. The boom operator transmitted "breakaway, breakaway, breakaway", and the B-47 commander took up a loose formation position off the tanker's right wing. The backup tanker, above and to the rear, made radio contact asking if they were in trouble, to which Lt. Burgess, the aircraft commander calmly replied "Roger, I'm on fire". At this point, the aircraft entered a gradual left turn which continued to get steeper, and turned into a spiral or spin. It was later determined that the left wing outboard of the burning engine had failed due to fire damage, before the crew could complete the "engine fire" drill. It was later found in Howard Pond some three miles from the crash site. The B-47 commander called "bail out! bail out!" but got no reply and spotted no parachutes. Witnesses on the ground, including over three hundred moviegoers at the Rumford Point Drive-In, saw the flaming aircraft spin down with burning pieces falling off. The fuel laden tanker crashed into Jonathan Smith Mountain near Route 26 in the Town of Newry. The aircraft was totally destroyed and all five crew members were killed.

Probable cause:
The investigation revealed that the accident was caused by a lubrication failure to the supercharger impeller shaft of the number one engine, leading to premature failure. The impeller, leaving the engine nacelle, did major damage and caused fuel leakage resulting in the severe fire and rapid structural failure of the wing.

Probable cause:
The Air Force Accident Investigation Board determined after a thorough investigation that the cause of the crash was due to a loss of lubrication to the bearings in the #4 engine turbo supercharger. That led to a failure of the turbo supercharger shaft. The turbine, once unloaded, accelerated to destruction and caused the uncontained catastrophic fire, due to what would presumably have been severed fuel lines or punctured tanks in the wing.
