Circumstances:
Shortly after takeoff from McConnell AFB, while climbing to a height of 500-700 feet, the captain sent a first distress call while the aircraft experienced a large amount of yaw. The crew elected to return for a safe landing and began to dump large quantities of fuel from the aircraft's refueling tanks. Shortly after this, the aircraft made a hard bank to the left, and began to enter a roll. Out of control, the airplane dove into the ground and crashed at the intersection of Piatt and 20th Street, just three minutes after takeoff, some 7 miles north-northwest of the airbase. The aerial refueling aircraft was loaded with 31,000 US gallons of jet fuel and the crash resulted in a large explosion and subsequent fire, which engulfed dozens of homes. The accident killed all seven crew members on board the aircraft and 23 people on the ground. In addition, 27 other people on the ground sustained injuries, three of which were serious. It was reported that the crew entry door was jettisoned and a B-52 Stratofortress bomber, which took off prior to the KC-135, may have blown a detached drag chute from an F-105 Thunderchief against the departing aircraft.
Probable cause:
Ten months after the accident, the U.S. Air Force issued an official accident report which stated that the crash was caused by "a rudder control system malfunction" which was impossible for the crew to overcome.

Circumstances:
The KC-135 was engaged in a refueling mission out from Larson AFB, Washington, and was carrying a crew of four. At an altitude of 26,000 feet, following a successful refueling mission of a USAF Republic F-105D-15-RE Thunderchief registered 61-0091, the crew of the KC-135 attempted to leave the area and the pilot-in-command made a turn to the right when the engine number four struck the cockpit window of the Thunderchief. Out of control, both aircraft dove into the ground and crashed in a mountainous area located in the Death Valley National Park. All four crew members on board the KC-135 as well as the pilot of the Thunderchief were killed.

Circumstances:
Following an uneventful refuelling mission of a Boeing B-47, the Stratotanker was returning to its base at Homestead, south Florida, some 1,125 km from its position. It was flying with a second USAF Boeing KC-135A-BN Stratotanker registered 61-0319 and carrying a crew of six. The first KC-135 was flying at an altitude of 36,000 feet while the second was following at an altitude of 35,500 feet. En route, both airplanes went into a low pressure area and apparently collided. All contacts were lost at 1230LT. SAR operations were conducted and some debris were found a day later some 480 km west of Bermuda. All 11 crew members were killed.
Probable cause:
Due to the lack of evidences, the exact cause of the accident could not be determined with certainty. However, it is believed that both Stratotanker collided in flight, maybe following a loss of speed and altitude from the first aircraft after it encountered downdraft or atmospheric turbulences.
