Boeing KC-135 Stratotanker

- On 4 October 1989, a KC-135A Stratotanker, 56-3592, from en route from Loring Air Force Base crashed into a hill along the west side of Trans-Canada Highway 2 2 mi (3.2 km) north of Perth-Andover, New Brunswick in Carlingford, New Brunswick due to an overheated fuel pump, killing all four crew members. After five accidents involving fuel pump overheating, crews were to keep 3000 pounds of fuel in the tank.
- On 31 January 1989, a USAF KC-135A, 63-7990, crashed on takeoff from Dyess AFB, TX after the water-injection system for the Pratt & Whitney J-57 engines failed and the remaining "dry" thrust was insufficient for flight at the takeoff gross weight. The mission was scheduled as a non-stop flight to Hickam AFB/Honolulu HI with an en route F-16 air refueling mission. In addition to the 7 crewmembers, 12 passengers, including military spouses, retired military members and one child, were killed. The aircraft was based at K I Sawyer AFB, MI.
- On 13 January 1999, a Washington Air National Guard KC-135E, 59-1452, crashed on approach in Geilenkirchen, Germany due to the horizontal stabilizer being in a 7.5 nose-up trim condition, killing 4 crew members.
- On 26 September 2006, a USAF KC-135R, 63-8886, was damaged beyond economical repair when it was struck by a Tupolev 154 of Altyn Air EEX-85718) while stopped on a taxiway after landing at Manas Airbase. The Tu-154 was taking off and its right wing struck the fairing of the KC-135R No. 1 engine. The force of the impact nearly severed the No. 1 engine, but destroyed a portion of the left wing and the resulting fire caused extensive damage to the KC-135. The Tu-154 lost about 6 feet of its right wingtip, but was able to get airborne and return to the airport for an emergency landing. The tanker crew had been directed to use a taxiway which was not usable for night operations and the controller failed to note that they reported "holding short" of that taxiway, rather than "clear of" that point. The crew of the KC-135 evacuated the aircraft without serious injuries.
