From the Wikipedia article
The Elvetham air crash occurred on 5 October 1945 when a Consolidated Liberator GR.VI aircraft, serial number KG867, of 311 Squadron Royal Air Force crashed at Elvetham, east of Hartley Wintney, Hampshire, following a fire in one of its engines and fuel starvation to another.
The aircraft was about five minutes into a flight from nearby RAF Blackbushe to Ruzyně Airport, Prague, Czechoslovakia. The crash killed all 23 people aboard: five crew, 17 official passengers and one stowaway.
All 23 victims were Czechoslovak citizens. They included ten women and five very young children. The crash was the largest single loss of life in an accident involving Free Czechoslovaks serving in the RAF Volunteer Reserve. After the crash the Czechoslovak Government switched the repatriation of its nationals from air to surface transport.
Flight history
Aircraft KG867 carried the marking PP-N. PP was the code for 311 Squadron and -N identified the individual aircraft. Its captain was Pilot Officer Jaroslav Kudláček, a 25-year-old from Chrudim in eastern Bohemia. He had 1,421 flying hours' experience, 512 hours of which were on four-engined aircraft. Kudláček had married a British woman, their first son had been born in October 1941 and the family was looking forward to the boy's fourth birthday. Kudláček had just returned from the Royal Hospital, Wolverhampton, where Mrs Kudláčková had given birth to their second son about 10 days previously.
KG867 was scheduled to make a 665 mi flight from Blackbushe to Ruzyně on Thursday 4 October to repatriate Czechoslovak service personnel and their families to their homeland. P/O Kudláček tried three times to take off but aborted each time because of a problem with one of the engines. After Kudláček aborted the third attempt the flight was postponed until the next day to let KG867 be examined and repaired.
One account states that the passengers were given temporary accommodation for the night. But another account, by Warrant Officer Pavel Svoboda of 311 Squadron, said "We spent a very unpleasant night, due to a lack of accommodation, especially the women with children."
By the next morning KG867's passenger manifest had been changed. Two 311 Squadron personnel who had been booked to fly as passengers – Warrant Officer Svoboda and WAAF Leading Aircraftwoman First Class Edita Sedláková – were displaced and their seats were reallocated to new VIP passengers (Marína Paulínyová and her entourage).
On Friday 5 October three Liberators including the rescheduled KG867 were to take off from Blackbushe. KG867 got airborne in good weather. Differing accounts suggest that it took off at either 1243 hours or 1420 hours. The aircraft made a normal circuit of the airfield as it turned to head for Prague. At the Liberator's cruising speed of 215 mph the flight could be expected to take more than three hours, so KG867 was carrying a substantial amount of fuel.
Investigation and cause
Cause
Débris was scattered at the crash site. Burnt pieces of cowling from the inner port engine were found about 1/2 mi before the point of impact. One of the starboard engines had been thrown about 200 yd away from the point of impact. Other wreckage was thrown up to 250 yd ahead of the point of impact.
The official investigation found:
The port inner engine caught fire due to a petrol escape from a ruptured pipe between the carburettor and oil dilution valve due to chafing. Ignition believed to be from exhaust pipe conduit to turbo supercharger.
The fuel pipe would then have been burnt away, which would have caused fuel starvation to the No. 1 (outer port) engine. With the port wing on fire and both port engines out of action, the aircraft would have been increasingly difficult to control.
The aircraft had no fire detection or warning devices. But it had two built-in CO2 fire extinguishers to fight engine fires. The extinguishers were not automatic. There was a control panel on the starboard side of the cockpit, from which the co-pilot would operate the extinguishers when instructed by the pilot. Investigators found that both of the extinguishers had been discharged. This suggested that a member of the crew, presumably the co-pilot, Warrant Officer Brož, had tried to extinguish the engine fire.
Access to the control panel was poor, as it was partly obstructed by an emergency pump for the aircraft's hydraulic equipment. The fire extinguisher control panel included selector switches for the co-pilot to select which of the four engines to douse with CO2. Investigators found that aboard KG867 the selector switch for the port engines was in the "off" position and the selector for the starboard engines was switched to extinguish the inner starboard engine. This suggested that in the emergency, Warrant Officer Brož may have selected to extinguish the wrong engine by mistake.
The presence of an unauthorised extra passenger aboard, LACW Sedláková, was not considered to have contributed to the accident.
