Circumstances:
The aircraft took off from Hong Kong-Kai Tak Airport bound for Jakarta at 0425 hours Greenwich Mean Time carrying 8 crew members and 11 passengers. The flight was uneventful until approximately five hours after take-off when a muffled explosion was heard in the aircraft while cruising at an altitude of 18,000 feet over the sea. Smoke started entering the cabin through the cold air ducts almost immediately and a localized fire was detected soon after on the starboard wing behind the number three engine nacelle. A rapid descent was commenced for ditching the aircraft and distress signals broadcast. In spite of fire fighting action, during which No. 3 engine was feathered, the fire spread very rapidly and caused hydraulic failure followed by electrical failure. During the final stages of the descent, executed under extremely difficult circumstances, dense smoke entered the cockpit reducing the visibility to almost nil. The aircraft impacted the water with the starboard wing tip, and the nose submerged almost instantaneously. Only three crew members survived the accident. The aircraft was destroyed. All passengers were Chinese and European journalists flying to Jakarta to take part to the Asia-Afro Bandung Conference.
Probable cause:
The cause of this accident was an explosion of a timed infernal machine placed in the starboard wheel well of the aircraft. This explosion resulted in the puncturing of No. 3 fuel tank and an uncontrollable fire. It is believed that the Chinese Premier Zhou Enlai was the target of this act of sabotage. His travel plans had been kept secret and he left China three days later.

Circumstances:
The crew started the approach to Gander Airport by night and in good weather conditions. Following a stabilized approach, the four engine aircraft landed normally on runway 32. After touchdown, the reverse thrust system were activated when the aircraft veered to the left. Despite several corrections on part of the flying crew such as braking action, movement on the nose wheel steering and power added on both left engines number one and two, the aircraft continued down the runway, overran, lost its undercarriage and came to rest into a ravine. While all 67 occupants were evacuated safely, the aircraft was damaged beyond repair.
Probable cause:
The approach configuration to Gander Airport was correct and the aircraft was stabilized until touchdown. No technical anomalies were found on the aircraft and all piloting techniques were normal. The analysis of the aircraft's path after touchdown did not show any trace of rough braking action. An exam of the pilot reports indicated that the aircraft was quite difficult to be maneuvered during a turn to the right. At the time of the accident, a lateral wind was blowing to 16 knots, which could be considered as a contributory factor.

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:
Following an uneventful flight from Jakarta, the crew started the descent to Singapore-Kallang in good weather conditions. On final approach to runway 06, the four engine aircraft christened 'Belfast' was too low and hit a sea wall, bounced and landed 80 yards past the runway threshold. On touchdown, the right main gear collapsed, the airplane veered off runway to the right, lost its right wing and came to rest in flames upside down. Seven crew members were injured while 33 other occupants, including all 31 passengers, were killed.
Probable cause:
The cause of the accident, i. e. the touchdown off the runway was attributed to the approach of the aircraft. While certain eye-witnesses describe the approach as normal, it was not normal relative to maintaining a steady glide path and rate of descent. The various rates of descent could be considered to be within normal bounds for a Constellation aircraft, but their general pattern was neither normal nor, having regard to the sea wall hazard, desirable. The extent to which the captain's original decision to land short on such a runway as 06 was an error can only be judged in relation to the wide range of expert pilot opinion as to what is a safe first point of touchdown. The fact that his first point of touchdown came back closer to the threshold markings than he originally intended can probably be attributed to a degree of tiredness of which he may or may not have been aware.

Circumstances:
The crew of Flight 627 consisted of Captain C. C. Foxworth Captain E. M. Engle, (first officer), Flight Engineer L. P. Devries, Flight Attendant A. J. Folli, and Flight Attendant A. L., Krause. On departure from the ramp, the gross weight of the aircraft was 95,838 pounds; allowable gross takeoff weight was 105,530 pounds. The load was distributed so that the center of gravity of the aircraft was within the approved limits. Flight 627 initially taxied out at 2345, bar 18, for takeoff from Runway 7R. This flight and a preceding flight returned to the ramp because fog drifted in and reduced visibility below the approved minimum of one-fourth mile while they were awaiting clearance for takeoff. 2 Neither flight was issued off clearance, although according to Captain Foxworth, they held at Runway 7R about 15 minutes. The captains of flights reported that when they arrived at Runway 7R the existing visibility was well over the required one-quarter mile, as they could ace beyond the far end of the 8,200-foot runway, and so advised the control tower. About 15 minutes after returning to the ramp, Captain Foxworth was advised by Eastern Operations that visibility had improved, and the flight again taxied out, following another Eastern aircraft, Flight 623W. While they were taxing, the tower suggested that takeoff be made on Runway 22L and advised that visibility to the south-southeast, from tower location, was three miles. Since both flights had taxied beyond this runway at the time this information was conveyed to them, they turned around and Captain Foxworth, now in the lead, took position for takeoff near the end of Runway 22L. The tower advised Flight 627 that the weather was now being reported as thin obscuration, one and one-half miles visibility, fog, and smoke. 4 Captain Foxworth opened the left side "clear-view" window for maximum visibility. The runway lights were turned to full intensity, and the landing lights of the aircraft were on. Captain Foxworth observed that visibility appeared to be at least one-fourth mile, and stare could be seen. He could see the runway border lights and down the runway centerline for some distance. He said that he was unable to see past the intersection. The engines were run up, cockpit checks completed, and airways clearance via Long Beach, Sully, and Woolf intersections was received. Takeoff clearance was issued at 0055, October 19. Captain Foxworth, flying from the left, made the takeoff using the runway border lights and centerline as visual reference guides. The first officer also maintained visual reference except when he briefly directed his attention to retraction of the landing gear. In the takeoff run the captain noticed that visibility was variable due to fog and seemed to get progressively worse, but later stated that he had "expected to come out on top almost any second" after becoming airborne; he did not go on instruments. Takeoff seemed normal. Shortly after calling for retraction of the gear. Captain Foxworth observed that air speed was approaching 110 knots. He said that he lost all ground references at about the intersection of Runways 19L, 25L, and 22L, at or shortly after becoming airborne. A few seconds later he heard the first officer shout a warning and they struck the ground while at takeoff power. A second or two after the first officer moved the landing gear handle to retract position and again directed his attention outside, he saw they were quite low, grabbed for the control wheel to pull the nose up, and simultaneously shouted a warning. He did not recall whether he got his hands on the wheel before impact. The aircraft struck the ground to the left of Runway 22L at Taxiway F. It bounced, and following the second impact skidded to a stop in an undeveloped part of the airport south of Taxiway G. An intense fire immediately developed in the left wing at No. 2 engine position. The pilots, flight engineer, and one passenger left through the crew door, located just to the rear of the cockpit on the right side; all other occupants exited in orderly fashion through the main cabin door at the left rear side of the aircraft.
Probable cause:
The Board determines that the probable cause of this accident was the captain's loss of visual reference and orientation when he encountered drifting fog shortly after becoming airborne on takeoff, and the resultant inadvertent assumption of a descending flight path. The following findings were reported:
- The general visibility figure given to the flight at about the tine clearance was issued for takeoff was ceiling unlimited, visibility one and one-half miles,
- From his position at the end of the runway, the captain estimated visibility to be about one-fourth mile, which was within the CAA-approved limits,
- A visual takeoff was made by the captain with the first officer also maintaining visual reference to the ground,
- Near the main intersection, slightly more than one-fourth mile from start of the takeoff run, the aircraft encountered fog which greatly reduced visibility,
- Although the aircraft became airborne, it did not penetrate the top of the fog
- The first officer saw the ground an instant before impact, but the aircraft struck before corrective action could be taken,
- There was no evidence of failure or malfunction of the aircraft, engines, or propellers before impact.

Circumstances:
The airplane left Paris-Orly in good weather conditions. However, few minutes later, the crew was informed about few turbulences over the Alps. While cruising by night at an altitude of 9,500 feet, the four engine aircraft hit the slope of Mt Cemet or Mt Cimet (3,020 meters high) located about 8 km northeast of Allos, in the department of Alpes-de-Haute-Provence. The wreckage was found at the altitude of 2,870 meters, about 150 meters below the summit. The aircraft disintegrated on impact and all 42 occupants were killed, among them the French violinist Jacques Thibaud and the French composer René Herbin.

Probable cause:
At the time of the accident, the aircraft was not following the track that has been assigned and was off course for unknown reason. It was understood that the airplane deviated from the prescribed flight plan, maybe following a navigation error, but this was not determined with certainty. Thus, the accident is the result of a controlled flight into terrain.

Circumstances:
While cruising at an altitude of 17,500 feet between Rhodes Island and Cyprus, the crew noted slight vibrations but was unable to localize them. Four minutes later, a loud bang was noted, an explosion occurred, a brutal depressurization occurred and the aircraft lost 1,000 feet. The captain, who was sleeping, joined immediately his seat, disengaged the automatic pilot system and started an emergency descent with a rate of 300-500 feet per minute. In the mean time, the copilot informed ATC he elected to divert to Nicosia Airport. The crew realized that the engine number three fell off and decided to shut down the engine number four and feathered its propeller. Eventually, the captain decided to ditch the aircraft on a calm sea about two NM off the Fethiye lighthouse. Ten minutes after landing, the empennage broke off and sank. Some passengers swum to the shore and the aircraft eventually sank two hours later. Three crew members were injured, 35 occupants were unhurt and four passengers were killed.
Probable cause:
In reference to all details collected by investigators, it is believed that the physical loss of the engine number three was caused by the loss of a propeller blade in flight. The cause of this failure could not be determined with certainty.

Circumstances:
En route to Bangkok, about 450 km from the intended destination, the crew informed ATC about vibrations coming from the engine number three. The flight was continued uneventfully until the descent was started. On final approach to runway 21, a propeller blade detached from the engine number three that caught fire and suffered severe vibrations. On touchdown, the right main gear collapsed and the airplane skidded for several yards before coming to rest in flames. All 44 occupants were evacuated safely before the aircraft christened 'Venlo' was destroyed by fire.
Probable cause:
Failure of a propeller blade during flight shortly before landing at Don Mueang Airport. This caused the loss of number three engine and fire to break out in the engine nacelle which could not be extinguished. When landing, the right main landing gear collapsed as a consequence of the fire.

Circumstances:
The four engine aircraft christened 'Malabar Princess' left Cairo-Almaza Airport at 0209LT on a direct flight to Geneva, completing an international service from Bombay to London, carrying 40 passengers and a crew of 8. All passengers were Indian and Pakistani marines who were joining their boat based in the harbor of Newcastle upon Tyne. About 20 minutes before its estimated time of arrival in Geneva-Cointrin Airport, while cruising at an altitude of 15,500 feet, the crew informed ATC that he was flying over Grenoble. The radio officer at Geneva Airport misbelieved this position and asked the crew to switch on 333 kHz for a direction finding check. The crew never contacted this frequency and the aircraft disappeared shortly later. As the airplane failed to arrive at Geneva Airport, SAR operations were conducted by the French, Swiss and Italian Authorities. The wreckage was found two days later, Sunday November 5, at an altitude of 4,671 meters, on the Rocher de la Tournette, about 300 meters from the Vallot Refuge. The aircraft disintegrated on impact and all 48 occupants were killed.
Probable cause:
At the time of the accident, a strong wind was blowing from the west and it is believed that the crew misinterpreted his position. The crew believed he was overflying Grenoble when in reality, the aircraft was approximately 111 km northeast of Grenoble, vertical to the Mont-Blanc Mountain range. In 1950, the area control center of Geneva-Cointrin was not equipped with a surveillance radar system. The only available systems were a medium-frequency direction finder and transmitters on shortwave (HF) with 4 available frequencies. At that time, Air India did not use the route Genoa - Torino - Geneva to avoid the Alps and preferred to fly the Nice - Gap - Grenoble - Geneva path marked by broadcast stations (BC) which unfortunately did not transmitted 24 hours a day. It appears that the accident was the result of a controlled flight into terrain mostly caused by unfavorable wind.
