Halifax serial: EB191

(RAF Photo, 1942)(Source Harold A Skaarup Web Page) A Royal Air Force Handley Page Halifax Mk. II Series I (Serial No. W7676), coded TL-P, of No. 35 Squadron, RAF, based at Linton-on-Ouse, Yorkshire in the UK, being piloted by Flight Lieutenant Reginald Lane, (later Lieutenant-General, RCAF), over the English countryside. Flt Lt Lane and his crew flew twelve operations in W7676, which failed to return from a raid on Nuremberg on the night of 28/29 August 1942, when it was being flown by Flt Sgt D. John and crew.

The Handley Page Halifax is a British Royal Air Force (RAF) four-engined heavy bomber of the Second World War. It was developed by Handley Page to the same specification as the contemporary twin-engine Avro Manchester.

The Halifax has its origins in the twin-engine HP56 proposal of the late 1930s, produced in response to the British Air Ministry's Specification P.13/36 for a capable medium bomber for "world-wide use." The HP56 was ordered as a backup to the Avro 679, both aircraft being designed to use the underperforming Rolls-Royce Vulture engine. The Handley Page design was altered at the Ministry to a four-engine arrangement powered by the Rolls-Royce Merlin engine; the rival Avro 679 was produced as the twin-engine Avro Manchester which, while regarded as unsuccessful mainly due to the Vulture engine, was a direct predecessor of the famed Avro Lancaster. Both the Lancaster and the Halifax would emerge as capable four-engined strategic bombers, thousands of which would be built and operated by the RAF and several other services during the War.

On 25 October 1939, the Halifax performed its maiden flight, and it entered service with the RAF on 13 November 1940. It quickly became a major component of Bomber Command, performing routine strategic bombing missions against the Axis Powers, many of them at night. Arthur Harris, the Air Officer Commanding-in-Chief of Bomber Command, described the Halifax as inferior to the rival Lancaster (in part due to its smaller payload) though this opinion was not shared by many of the crews that flew it, particularly for the MkIII variant. Nevertheless, production of the Halifax continued until April 1945. The operational statistics from the Bomber Command War Room Manual, state 82,773 operational sorties 2,232 aircraft lost of which 1,833 were missing, in addition there were 365 anti submarine patrols with 4 aircraft lost. Halifax laid 9,572 mines according to the war manual, daily reports total 9,550 being 851x1000, 6,450x1500 and 2,248x1850 pound mines.. The Halifax was also flown in large numbers by other Allied and Commonwealth nations, such as the Royal Canadian Air Force (RCAF), Royal Australian Air Force (RAAF), Free French Air Force and Polish forces.

Unit Desciption

1664 HCU (1664 Heavy Conversion Unit)

The Heavy Conversion Unit (HCU) trained bomber crews who had finished an Operational Training Unit to fly the four-engined heavy bombers (Stirling, Halifax and Lancaster) before they joined a squadron.

From the unit's own diary (Operations Record Book): the unit was at RCAF Station Croft until 6 December 1943; the main movement to Dishforth took place on 7 December 1943 and the unit became part of RCAF Station Dishforth. The diary file ends in December 1943.

The Croft station diary has the unit at Croft from June to December 1943; in 1944 it names the unit only as receiving personnel and aircraft from the Croft squadrons (aircraft transferred from 434 Squadron), never as resident.

The Dishforth station diary records the arrival of No. 1664 Conversion Unit from Croft in December 1943.

The unit's diary at Dishforth records two losses on training flights in 1944: on 14 October 1944 Halifax II HR802 failed to return from a cross-country 'bullseye' exercise (six aircraft searched the sea on the 15th without result and it was posted missing), and on 15 November 1944 a Halifax lost on a night cross-country at 18,000 feet collided with an aircraft of the Wombleton unit (F/L Garvie and crew).
