This version was an electronic reconnaissance aircraft used in Arctic conditions. It crashed into Lake Mead, during a research flight. The crew of five was able to scramble away before the plane sank. It has been located by sonar in 170 feet of water, largely intact except for 3 missing engines (number two, three and four). The flight was for a secret missile guidance system that allowed navigation by tracking of the Sun. A low pass over calm water with pilot error put it into the lake. The aircraft plummeted from high altitude down to as close to the lake as possible. Unfortunately, Captain Robert M. Madison lost his depth perception and plowed the huge plane into the lake at 230 mph. The impact tore off all but one of the engines and sent the plane skipping along the lake surface. When she eventually stopped, she began to take on water and started to sink. Fortunately, all of the crew was able to escape into life rafts and wait for rescue.

The crew was forced to ditch the aircraft into the Mediterranean Sea some 130 km south of Marseille. All twenty occupants were rescued while the aircraft sank and was lost.

En route, an engine failed, forcing the crew to attempt an emergency landing south of Tel Aviv. While the aircraft was damaged beyond repair, all five occupants survived. The captain Murray Weissberg was recovered later while the second pilot Spencer Boyd and all three passengers were captured by Palestinians soldiers and later executed.

Crashed in unknown circumstances in Cumbica, south of the São Paulo-Guarulhos Airport. All 12 crew members were killed.

While cruising in foggy conditions, the aircraft hit the slope of a mountain located 17 km from Coronel Pringles. The aircraft was destroyed by impact forces and a post crash fire and all five crew members were killed.

Crashed 2 miles southwest of Offutt AFB following an engine failure. The crew fate remains unknown.

During a night approach to Greenville, the aircraft crashed in flames and burned. At least one crew member was killed in the accident.

The approach to Wiesbaden-Erbenheim AFB was completed by night and poor weather conditions. On final, the aircraft hit tree tops and crashed in a wooded area located 1,6 km short of runway 25 threshold. Both pilots were injured while the aircraft was damaged beyond repair.

The four engine aircraft left Malta-Luqa Airport bound for RAF Northolt with four passengers and a crew of three on board. While approaching the London area, the crew encountered low visibility due to poor weather conditions. The crew was cleared to descent to 3,000 feet when the aircraft collided with a Scandinavian Airlines System (SAS) DC-6 registered SE-BDA. Inbound from Amsterdam, this second aircraft was carrying 25 passengers and a crew of 7. Following the collision, both aircraft went out of control, dove into the ground and crashed in a wooded area located in Northwood, about 4 miles north of RAF Northolt. Both aircraft were destroyed and all 39 people were killed. Among the passenger of the York was Sir Gerard Edward James, High Commissioner in Malaysia for Her Majesty the Queen of England.

The left engine caught fire during start up. The crew called the fire brigade and evacuated the aircraft. The fire was extinguished but the aircraft was partially destroyed by fire and considered as damaged beyond economical repair.
