From the Wikipedia article

The Airwork Handley Page Hermes accident near Trapani occurred on 25 August 1952. On that day, an Airwork Ltd. Handley Page HP.81 Hermes IVA coming from Blackbushe Airport and on a charter flight to Khartoum with a stopover in Malta had to ditch at night in the Mediterranean Sea off Sicily after an engine and electrical failure had occurred during the flight. Of the 57 occupants of the Handley Page Hermes, seven occupants were killed.

Accident sequence

The aircraft lifted off from Blackbushe Airport on 24 August 1952 at 20:25 local time, with 51 passengers and six crew members on board. The flight proceeded without particular incident until, at 01:25 local time on 25 August 1952, the aircraft was about 20 miles west of Trapani. At this point engines No. 2 (left inner) and No. 3 (right inner) were running abnormally and were therefore deliberately shut down and their propellers feathered. Since this meant that no generators were running any longer, only the electrical power stored in the batteries remained, which was gradually used up by the use of the radio equipment to send the emergency signals. Subsequently, engines No. 1 (left outer) and No. 4 (right outer) also ran abnormally. At around 01:30 local time a ditching was carried out in the sea between the port of Trapani and the island of Formica. Four passengers drowned after the ditching; two further passengers and a flight attendant were missing.

Investigation and cause

Cause

The cause of the accident was determined to be the failure of one or both of engines No. 2 and 3., located on the inboard sides of the wings. The cause of the engine failure could not be determined.

The following were determined as contributing factors:

On the basis of their knowledge of an accident with the same aircraft type that had occurred shortly before due to engine failure, the pilots concluded that this was also a case of engine failure

The electrical generators had been put out of operation after engines No. 2 and 3 were shut down

The batteries installed in the aircraft were unsuitable for maintaining normal flight functions or sending emergency signals in the event of a generator failure

The pilots and flight attendants had only limited experience with the aircraft type being flown

The flight crew had only limited training for emergencies of this kind

Emergency procedures, were, particularly by the flight attendants, not properly followed

Life rafts were either missing or were not used.

Seat belts failed

The board of inquiry was of the opinion that only one of the two engines that had been shut down (No. 2 and 3) had failed by itself and that the failure of the other engine was due to an error by the flight engineer.
