Circumstances:
The takeoff from Southampton was attempted by night. During the takeoff roll on the Solent, the seaplane was unstable and the captain was unable to maintain the aircraft on the right course so he decided to abandon the takeoff procedure. A float located on the left wing hit the water surface and the left wing was submerged to the outer engine. All 31 occupants were quickly rescued and were uninjured while the aircraft sank.
Probable cause:
The accident was due to an error of airmanship by the captain in that he did not ascertain the crosswind component and in consequence attempted to take off under conditions with which he could not contend. The following factors were considered as contributory:
- The control officer misinformed the captain of the relationship between the wind and the flare path at the time of takeoff,
- The sudden deterioration of the weather conditions during the takeoff procedure.

Circumstances:
The crew was performing a flight from Gibraltar to Lisbon to assist the crew of a RAF Halifax that diverted to Lisbon. While flying over the Atlantic Ocean, weather conditions deteriorated and the pilot decided to divert to Tangiers and later to Cadix. As the aircraft was short of fuel, he was forced to ditch the airplane 56 km south of Cadix and the radio operator was able to send a brief message before the aircraft impacted water and sank. All three crew members and two passengers took refuge in a dinghy while a third passenger drowned.

Circumstances:
About 150 nm from his destination, the crew informed ground about the ETA in Santa Maria-Vila do Porto Airport at 0245LT. Few minutes later, the captain changed this ETA to 0255LT. During the final approach completed by night but in good weather conditions, while at an altitude of 3,000 feet, the captain confirmed to ATC that he had the runway in sight and was approaching in VFR mode. Shortly later, the aircraft hit the slope of Mt Redondo (about 900 meters high) located few km from the airport. The aircraft was destroyed by impact forces and a post crash fire and all 48 occupants were killed. Among them were the French boxer Marcel Cerdan, the French violinist Ginette Neveu and her brother Jean Neveu, pianist, and Kay Kamen, artistic director by Walt Disney Studios.

Suzanne Ruig, stewardess.
Probable cause:
Without rejecting with an absolute certainty the possibility of a misinterpretation, the Commission of Inquiry believes that the inaccurate navigation of the aircraft is due to a sudden failure, at the end of the flight and unsuspected by the crew, of some elements from the receiving direction finding system, abnormal radio propagation operation or become defective. This cause combined with overconfidence due to good weather conditions in the arrival zone, conditions which have not prompted the captain to check his radio point as it would have done under unfavorable weather conditions. A visual confusion in darkness finally resulted.

Circumstances:
On final approach to Dakar-Yoff Airport, the captain decided to go around due to low visibility causes by poor weather conditions. A second and a third attempt to land were aborted few minutes later. During the fourth attempt, while short of fuel, the aircraft landed hard and the undercarriage were sheared off. The aircraft slid on its belly for several yards and came to rest, broken in two. Six passengers were killed while nine other occupants were injured.
Probable cause:
Regarding the flight plan, there was too great errors in the ETA and the endurance was inexact. Lack of decision on the part of the pilot who, after his second attempt to land, and in view of his insufficient petrol reserve, should have carried out the diversionary plan.
The lighting of the runways was inadequate: there were no approach lights and there are no wireless facilities for landing in bad visibility at Dakar-Yoff Airport.
Contributory Causes:
Difficulties in exchange of radio telephony communications between the control tower and the aircraft,
Insufficient knowledge of the English language by the controllers in the tower, according to the Americans and British,
As regards to the crew, there certainly appears to have been a slight nervousness during the attempts to land,
The danger to passengers in the case of cabin fuselage below the wing in the event of a forced landing elsewhere than on a runway,
Lack of knowledge of the alternate airfield of Thies by BSAA crews. Thies was given on the old general aeronautical maps but at the time of the accident, no schedule for this aerodrome has yet been published by the Aeronautical Information Section. This schedule was available following the publication of the final investigation report.

Circumstances:
The aircraft left Paris Le Bourget Airport at 1045LT and Bordeaux-Mérignac at 1330LT. The crew started the descent to Lisbon Airport in poor weather conditions with low clouds and fog. While approaching from the west, the aircraft hit the slope of Mt Peninha located in the Sintra Mountain Range, about 30 km west of the airport. The aircraft was destroyed by impact forces and a post crash fire and the wreckage was found about 15 meters below the summit. A passenger was seriously injured while 19 other occupants were killed, among them 8 members of the French Orchestra 'Ars Rediviva' directed by Claude and Claire Crussard.
Crew:
Oscar Porta, pilot,
Michel Eyquem, copilot,
René Montel, radio navigator,
R. Anglès, mechanic,
Anne-Marie Dupuy, stewardess.
Probable cause:
It appears that the radio guidance system at Lisbon Airport failed for about 15 minutes while the crew was approaching the city from the west. At that time, the visibility was reduced due to foggy conditions and the crew was unable to locate his position with certainty. Due to poor visibility and lack of ground assistance, the crew did not realize his altitude was insufficient.
