Milwaukee-General Billy Mitchell Wisconsin

The approach to Milwaukee-General Billy Mitchell Airport was initiated in poor weather conditions with clouds down to 200 feet and an horizontal visibility limited to half a mile. On final, the four engine aircraft was too low, struck the ground and crashed in flames half a mile short of runway threshold. The aircraft was destroyed by a post crash fire and seven occupants were injured while four others were killed.

Stephenville Newfoundland & Labrador

The crew was engaged in a local training flight at Stephenville-Ernest Harmon Airport. Following several circuits, the crew started a night approach to runway 09 with a tailwind component. Apparently due to a wrong approach configuration, the airplane landed too far down the runway. After touchdown, the pilot feathered the propeller on two engines but the airplane was unable to stop within the remaining distance. It overran, struck several approach lights and eventually came to rest in a pond located short of runway 27 threshold. All five crew members were killed.

Hamilton All Bermuda

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. Source: Facebook page Bermuda Air Collision

Newry Maine

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. Crew: Lt William Burgess, pilot, Lt Lewis Turner, copilot, Lt Raymond Kisonas, navigator, M/Sgt Harold Young, flight engineer, T/Sgt Robert Costello, boom operator.

Westover AFB Massachusetts

The aircraft, assigned to the 384th AREFS, departed from Westover AFB on a refueling mission. The KC-97 collided with a B-52 during refueling at an altitude of about 15,000 feet. The aircraft lost the whole left horizontal stabilizer and elevator, the rudder was missing and the upper fourth of the vertical stabilizer. They made a no-flap, electrical power off landing at night at Dow AFB. Two crew members on the B-52 parachuted to safety. The plane remaining crew members continued to Springfield-Westover AFB, MA (CEF) where a safe landing was made. Source: https://aviation-safety.net/database/record.php?id=19591214-0

Mt Big Shanty New York

The airplane was on a refueling mission and departed Westover AFB at 1330LT bound for Griffiss AFB, Rome, New York. Following an uneventful mission, the crew started the descent to Griffiss AFB but was instructed to follow a holding pattern because a fighter that was short of fuel must land immediately. Twenty-five minutes later, while cruising in poor weather conditions (freezing rain and snow), the airplane struck the snowy Mt Big Shanty (701 meters high) located about 70 miles northeast of Griffiss AFB, in the Adirondack Mountain Range. Rescuers arrived on scene in the early morning of January 24. All seven crew members have been killed, among them Maj Charles D. Mellinger, pilot, and 1st Lt Fred Defrench, copilot.
