Capt. Jacob Pruett Jr., Capt Orion Clark, Brigadier General Richard Ellsworth, Major Frank Wright and a crew of nineteen took off in RB-36H, 51-13721 of the 28th Strategic Reconnaissance Wing (Heavy) from Lajes Airdrome in the Azores at 0000 Zulu (11:00 PM Azores time) on March 18, 1953. Their destination was their home base of Rapid City Air Force Base, South Dakota. Their flight path took them across the Atlantic Ocean and over Newfoundland. The flight was expected to take 25 hours. The pre-flight weather briefing indicated that their flight path would take them to the south of a low pressure zone. The counter-clockwise rotation of the low would produce headwinds that were forecast to average 17 knots from 300 degrees. General Ellsworth and Major Wright were not current in take-offs and landings, so Capt. Jacob Pruett Jr. and Capt Orion Clark were probably at the controls during the take-off. Major Wright then moved into the pilot's seat on the left and General Ellsworth got into the co-pilot's seat on the right. Major Wright and General Ellsworth flew the over water portion of the flight about 1,000 feet off the water for best range performance. They monitored their altitude above the water with the radar altimeter as they flew through the darkness. The navigator intended to turn on the mapping radar an hour before the time that he expected the RB-36H to reach land. The pilots planned to climb to an altitude that would carry the RB-36H safely over the mountains of Newfoundland while they were still 20 miles from land. Most of the flight was flown in overcast conditions that prevented the navigator from using the sextant for a celestial observation to determine the true position of the airplane. The low pressure zone moved south of its predicted position before the RB-36H reached its vicinity. The airplane passed to the north of the low. Instead of the anticipated headwinds, the airplane encountered tailwinds that averaged 12 knots from 197 degrees. Ocean station delta received a position update from the RB-36H at 0645Z. The navigator reported that the ground speed of the airplane was 130 knots. The position was in error by 138 nautical miles, and the true ground speed was closer to 185 knots. The RB-36H reached Newfoundland about 1-1/2 hours earlier than expected. The crew made no attempt to contact air defense when they were fifty miles off shore. The navigator did not turn on the radar. The pilots continued to fly at low altitude. In the last twenty minutes of the flight, the ground speed averaged 202 knots. The visibility was less than 1/8-mile as the airplane flew straight and level through sleet, freezing drizzle, and fog. At 0740Z (4:10 AM Newfoundland time), thirty miles after crossing the coastline the RB-36H struck an 896-foot tall ridge at an elevation of 800 feet. The six whirling propellers chopped the tops off numerous pine trees before the left wing struck the ground. The left wing ripped off of the airplane, and spilled fuel ignited a huge fireball. The fuselage and right wing impacted 1,000 feet beyond the left wing. The entire crew was killed on impact. Wreckage was strewn for 3/4-mile across the hillside. U. S. Air Force 1st Lt Dick Richardson heard the RB-36H approaching his cabin at Nut Cove. The sound of the engines stopped suddenly, to be replaced by a loud explosion. Richardson reported that, "Everything lit up real bright". He could see a fire burning on the hillside above. He woke up the other men on the hill. They boiled up the kettle and sent a search party up to the crash site through deep snow. They found no survivors. Following this tragedy, the Rapid City airbase will be renamed Ellsworth AFB to honor the general.

Crash landed at Goose Bay-Ernest Harmon Airport for unknown reason. There were no casualties but the aircraft was written off.

On approach to Goose Bay following a transatlantic flight from RAF Fairford, the aircraft was misaligned and crashed in a wooded and hilly terrain located 26 km southwest of the airport. Fifteen crew members were injured and two others (seated in the rear part of the cabin) were killed.

Crashed in unknown circumstances few minutes after its takeoff from Goose Bay. SAR operations were conducted but eventually abandoned after few days as no trace of the aircraft nor the crew was found. The wreckage was eventually found in a remote area on June 23, 1953.

While flying northeast of Vancouver, the twin engine aircraft hit a snowy mountain slope located near Widgeon Lake, west of Pitt Lake. Debris were found few days later and all five crewmen were killed.

En route to Kemano, weather conditions deteriorated. The pilot decided to reduce his altitude and attempted an emergency landing when the seaplane crashed into the Kingscorner Point located north of Butedale. All five passengers were killed while the pilot survived.

On final approach to Stephenville Airport by night, the four engine aircraft hit the ground and crashed 1,5 km short of runway threshold. A passenger was rescued while 13 other occupants were killed. For unknown reason, the crew was completing the approach at an insufficient altitude.

While cruising at an altitude of 1,800 feet, the twin engine aircraft hit the slope of a mountain located in Halfmoon Bay. The wreckage was spotted by the crew of a RCAF helicopter three days later. A day later, on December 9, rescuers arrived on site. The pilot, sole on board, was killed.

During an instrument approach to Comox Airbase, while flying in poor weather conditions, the aircraft went out of control and crashed in a swampy area. All seven passengers were killed while both pilots were injured. It was later confirmed by the RCAF that the Lancaster was scheduled on this flight to replace a Canso that suffered an engine failure earlier that day.

Crashed on takeoff at Le Havre-Saint-Pierre Airport for unknown reason. Both crew members were injured and the aircraft was damaged beyond repair.
