No. 428 Squadron RCAF
No. 428 Squadron RCAF was the ninth long-range heavy bomber Article XV squadron formed overseas during the Second World War at RAF Dalton in Yorkshire, England on November 7, 1942. The squadron was initially assigned to No. 4 Group RAF. With the creation of No. 6 Group RCAF, the squadron was reallocated on January 1, 1943 operating with it until April 25, 1945.
426 Transport Training Squadron
No. 426 Squadron RCAF was created during the Second World War as a result of the British Commonwealth Air Training Plan to supply aircrew for the war in Europe. It first formed at RAF Dishforth, England on October 15, 1942, with Vickers Wellington Mk IIIs and Mk Xs. The squadron was used as bomber unit in No. 4 Group RAF, RAF Bomber Command. Its first operational mission occurred on the night of the 14th and 15 January 1943, when seven Wellingtons bombed Lorient. The squadron used to fly by night, principally over Germany. Unlike the other RCAF Wellington squadrons it did not go to Tunisia in that year, but remained operating over Germany. That year the squadron transferred to No. 6 Group RCAF. In June of that year it moved to RAF Linton-on-Ouse, where it re-equipped with the Bristol Hercules-engined Avro Lancaster II. With this type it soon resumed the offensive, and continued with the night campaign from Linton for the next ten months. On April 1944 it began to re-equip with Handley Page Halifax IIIs and VIIs, and for the next year continued to operate with these types as part of No. 6 Group.
