Circumstances:
The aircraft was performing a flight from Patuxent River NAS to Port Lyautey, Morocco, with an intermediate stop at Lajes, carrying 21 crew members and 21 passengers, among them civilians and children. At 2330LT, the crew informed ATC about his position 400 miles east of Baltimore (Maryland), this was the last radio transmission. About an hour and a half later, while cruising at an altitude of 17,000 feet, the aircraft went out of control and crashed into the Atlantic Ocean without any distress call on part of the crew. SAR operations were conducted on a large area but were suspended six days later due to poor weather conditions. No trace of the aircraft nor the 42 occupants was found. It was reported by the board that the aircraft was also carrying 111 life vests, 46 exposure suits, 660 paper cups and 5 life rafts. All elements supposed to float. However, no trace of them was ever found.
Probable cause:
It is the opinion of the Board that R7V-1 registered 128441 did meet with a sudden and violent force, that rendered the aircraft no longer airworthy, and was thereby beyond the scope of human endeavor to control. The force that rendered the aircraft uncontrollable is unknown. The possibility of structural failure during transit of frontal weather cannot be discounted in this accident, but the possibility appears remote.

Circumstances:
The crew was performing a transatlantic flight from Hamburg to Bogotá with intermediates stops at Frankfurt, Paris, Madrid, Lisbon, Ponta Delgada and Hamilton. While approaching Ponta Delgada by night, the crew was informed about fog at destination and as the visibility was below minima, the captain decided to divert to Lajes. After a uneventful refueling stop, the crew took off from Lajes Airport, bound for Hamilton, Bermuda, at 0237LT. Three minutes after its departure from runway 34, while climbing, the four engine aircraft hit the slope of a mountain and burst into flames about 9 km southwest of the airport. The aircraft disintegrated on impact and all 30 occupants were killed.
Probable cause:
The probable initial cause of the accident was the failure of the pilot to carry out the normal climb-out procedure following take-off from runway 34 on a flight to Bermuda and his having made a turn to the left instead of to the right, thus flying into the mountains instead of turning out to sea.
The possibility of the aircraft having been forced to make a left turn may be disregarded since, from examination of the wreckage, it appears that no mechanical failure occurred.
The procedure to be followed had been duly explained to the crew both at the briefing and in the instructions which were certainly given by the tower. It is pointed out, moreover, that the chart of Lajes in the route manual supplied to the crew clearly shows that all turns must be made towards the Northeast.
The question of a right turn following take-off appears to have been deemed a secondary matter by the crew members who called at the briefing office. They simply established that they had to proceed directly to Ponto Sul in order to avoid a collision with the mountains, the highest point of which reached 7 615 feet.
From the heading presumed to have been flown by the aircraft before it crashed, it is quite apparent that the pilot did, in fact, intend to proceed to Ponto Sul. He appears not to have realized, however, that to do so he had to turn eastward towards the sea and not to the west over the land.
It is necessary to mention that, according to his company, this was the first time that the captain had landed at Lajes and that at Santa Maria, where he had already landed several times, the take-off procedure for flights towards the Northwest in the direction of Bermuda also involves a turn towards the sea. The turn at Santa Maria is made to the left, however, as the airport is located on the extreme west of the island.
The point known as Ponto Sul is shown on the reproduced 1:l 000 000 chart at Fig. 30. Examination of this chart will immediately explain the reason for the adoption in the Azores control area of the standard procedure whereby aircraft are required to fly over this point before proceeding towards Bermuda, in order to avoid the high ground on Terceira, S. Jorge, Pico and Faial Islands.
Since Lajes Airport is located in the extreme Northeast of the Ihla Terceira, the requirement, for reasons of safety, to turn to the east and out to sea in order to avoid the mountains on the island needs no special comment, being obvious in view of the nature of the terrain.

Circumstances:
While cruising at an altitude of 12,000 feet off the Isle of Man, the crew informed ground about vibrations and icing conditions. The pilot obtained the permission to reduce his altitude to 8,000 feet when few minutes later, he sent a brief message saying he was losing control of the aircraft that crashed into the Irish Sea about 6 miles south of Barrow-in-Furness. SAR operations were conducted but eventually suspended after few days as no trace of the aircraft nor the seven crew members was found. At the time of the accident, weather conditions were poor with wind and snow falls. The sea was rough and SAR operations were difficult to conduct.

Probable cause:
The exact cause of the accident could not be determined with certainty. However, the assumption that the loss of control was caused by an excessive accumulation of ice on all critical surfaces and engines was not ruled out.

Circumstances:
The crew was performing a ferry flight from Dover, Delaware, to Frankfurt-Main Airbase with intermediate stops in Lajes, Azores Islands, and Paris-Orly. On final approach, the airplane went out of control and crashed in flames in Choisy-le-Roi, less than four km from the runway threshold. All six occupants were killed.
Probable cause:
It is believed that the loss of control may have been caused by the loss of the rear clam shell door which detached on final approach and struck the horizontal stabilizer, causing the failure of the empennage and the subsequent crash of the airplane.

Circumstances:
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.

Probable cause:
The accident investigation board recommended that a forward looking radar should be developed to provide warning of high terrain ahead of an airplane. Navigators were instructed to scan for land with the radar every six minutes and pilots were instructed to climb to a safe altitude whenever the estimated position of the airplane was within 200 miles of land.

Circumstances:
While cruising at an altitude of 11,000 feet enroute from Hamilton to Lajes, Azores Islands, the manifold pressure on the right engine dropped from 30 to 17 inches. The captain decided to return to Hamilton (Bermuda) for a safe landing but twenty minutes later, the right engine backfired while the manifold pressure increased to 20 inches. In such conditions, he decided to shot down the engine and feathered its propeller. Less than an hour later, while flying at an altitude of 3,000 feet, the left engine started smoking and lost oil. The crew eventually decided to ditch the aircraft near the weather station 'Echo' located in the Atlantic Ocean, east of the Bermuda archipelago. The aircraft sank and was lost while all ten crew members were rescued and evacuated by the crew of the USCGC Coos Bay.
Probable cause:
Double engine failure.

Circumstances:
The four engine aircraft was on its way from Stansted to Kingston, Jamaica, carrying RAF personnels and their family members. It left Lajes Airport in the Azores Islands at 2325LT on February 1st. While approaching the Canadian coast by night, the crew issued a brief emergency message whose content remains unclear. Shortly later, the aircraft crashed into the Atlantic Ocean, about 500 km southeast of Saint John's (approximately 46°15 latitude North and 46°31 longitude West). As the airplane failed to arrive in Gander, SAR operations were conducted but eventually suspended few days later as no trace of the aircraft nor the 39 occupants was found. Weather conditions at the time of the accident were considered as good.
