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.
No. 3 Squadron RCAF
No. 3 (Operations) Squadron was formed at Rockcliffe, Ontario on 1 April 1925 under the control of RCAF headquarters, one of four squadrons authorized to carry out missions in support of government agencies. It soon moved to Shirleys Bay a month after its formation. Commanded by Squadron Leader A.B. Shearer, it flew forestry patrols over Ontario and Quebec to support civil government, in addition to "operating a test and development centre for new aircraft and photographic equipment." Flight Lieutenant R.S. Grandy replaced Shearer on 12 January 1926, and would lead the squadron for the rest of its military career. The squadron was equipped with the Curtiss HS-2L, Vickers Viking, Canadian Vickers Varuna, and Canadian Vickers Vedette flying boats, as well as the Avro 552A floatplane. Due to opposition to the RCAF performing civil operations, the squadron was transferred to the nominally civilian Directorate of Civil Government Air Operations on 1 July 1927 and its designation lapsed. It was retroactively redesignated as No. 3 (Service) Squadron on 1 April with A Flight nominally consisting of Armstrong Whitworth Siskin fighters, B Flight consisting of Armstrong Whitworth Atlas army cooperation aircraft, and C Flight consisting of Fairchild 71 and Bellanca Pacemaker. The squadron was reformed a year later as No. 3 (Advanced Training) Squadron, but due to a lack of aircraft, funding, and personnel it only existed on paper.
