United States of America

En route, the crew reported that the right engine failed and elected to return to Norfolk-Chambers Field NAS. On approach, the left engine failed as well and the airplane stalled and crashed into the Willoughby Bay. Four crew members were killed while six others were seriously injured.

The pilot, sole on board, was returning to his base at Nome after having flown passengers to Kotzebue. After takeoff, a fire erupted in the cabin and the pilot elected to return for an emergency landing. While completing a sharp turn at low height, the right wing struck a telephone pole and was sheared off. Out of control, the airplane crashed and burned, killing the pilot. It was reported that cabin gas heater burst into flames after rotation.

While cruising in marginal weather conditions at an altitude of 8,500 feet, the airplane struck trees and crashed on the slope of the Panther Peak. The aircraft was destroyed and both crew members were killed. At the time of the accident, the crew was not following the assigned route from Burbank to Seattle-Tacoma Airport for unknown reason. Apparently following a navigation error, the aircraft was 45 miles to the east from the intended route and at an insufficient altitude of 8,500 feet instead of the minimum 14,500 feet required.

En route from Ellensburg to the McChord AFB, the aircraft crashed in unknown circumstances in a mountainous area covered by snow. As the aircraft failed to arrive at destination, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the crew was found. The following summer, walkers found the wreckage in an isolated area.

The crew was performing a flight from McChord AFB, Washington, to Kodiak, with a load of various goods for a total weight of 34,500 pounds. While approaching the Kenai Peninsula, the crew informed ATC about engine problems and elected to divert to Anchorage. Few minutes later, the captain reported he was unable to maintain a safe altitude when, at an altitude between 3,000 and 4,000 feet, the airplane struck the slope of a mountain located in the Petrof Glacier, about 26 miles southeast of Homer. The wreckage was found a day later and all nine occupants were killed.

During a night approach to Bristol-Tr-Cities Airport, the airplane was too low and struck the slope of Mt Holston located 15 miles from runway 27 threshold. The airplane was destroyed by impact forces and a post crash fire and all ten occupants were killed. The evidence indicates Flight 308 departed Nashville, Tennessee, with an inoperative radio compass. Although the flight was cleared by way of low frequency airway Green 5, it does not appear that the facilities defining this airway were used. Upon arriving in the Tri-Cities area the aircraft was east of its intended track and erroneously identified the reporting point from which an ILS approach procedure was to be initiated. During the instrument approach, which was conducted in snow showers, the flight missed the outer marker. The approach was continued under instrument conditions without utilizing the VOR facility which would have been of assistance in confirming the flight's position. Without having clearly established his position, the pilot flew 15 miles beyond the outer marker and descended to an altitude too low to clear high terrain in this area.

Crashed in unknown circumstances somewhere in the USA between August and December 1958. According to another source, the aircraft may have crash landed at Jeddah, in Saudi Arabia, on February 1st, 1959.

En route to Boston, the crew encountered poor weather conditions with icing. Both carburetors suffered icing in flight and both engines failed. The airplane went out of control, dove into the ground and crashed in a field located five miles southwest of Woonsocket. The airplane was destroyed upon impact and all seven occupants were killed.

The crew was completing a local night training mission at Altus AFB. After several circuits, the crew started a new GCA approach when the pilot-in-command requested climb to altitude for another jet penetration. Problems with stabilizer trim during overshoot caused the aircraft to lose height and to crash about 4 miles north of the airfield. A crew member bailed out and was rescued while eight other occupants were killed.

The aircraft took off at 0445 on an "Operation Headstart" refueling mission. Headstart was the 42nd Bomb Wing's operation that "proved" the concept of airborne nuclear alert with B-52 aircraft for SAC. Before take-off, the crew was notified of a no-notice Standardization Board evaluation, so in addition to the crew of 4, there was an Instructor Pilot, Instructor Navigator, and Instructor Boom Operator aboard. Upon returning to the Loring AFB area, the aircraft was cleared to make a GCA approach from the south for a touch and go landing. The aircraft touched down about 2500 feet down the runway, applied power and became airborne at about the 7000 foot mark. Because of the aircraft's weight, air temperature and the forces involved in a touch and go landing, the Pilot got the tanker airborne in a condition where there was a 35 knot gap between adequate lift for take-off and adequate airflow over the ailerons for roll authority. The aircraft rolled to the right, striking the Number 4 engine which failed due to fuel control unit damage and jamming the right aileron in a 5 degree up position. The aircraft entered a nose high, right wing low attitude and cartwheeled into the woods about 1000 feet from the runway. It broke into several major sections and burned. The Instructor Navigator and Instructor Boom Operator were able to egress the burning wreckage but the Instructor Navigator died several weeks later as a result of his burns.
