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. 2 Squadron RCAF
No. 2 (Operations) Squadron was formed at High River, Alberta on 1 April 1925 under the control of RCAF headquarters, one of four squadrons authorized to carry out missions in support of government agencies. Commanded by Squadron Leader A.A.L. Cuffe, it flew forestry patrols over Alberta to support civil government with sub-bases at Pincher Creek and Eckville. Flight Lieutenant R. Collis replaced Cuffe on 19 October 1926, and would lead the squadron for the rest of its military career. Equipped with the de Havilland DH.4, Avro 552A, and Avro 504N, it tested two Armstrong Whitworth Siskins between 22 June and 14 July 1927. Of the latter, one crashed on 28 June with the loss of its pilot and the other was returned to Camp Borden. 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. Retroactively redesignated as No. 2 (Training) Squadron on 1 April, the squadron was reformed a year later as an advanced training unit, but due to a lack of aircraft, funding, and personnel it only existed on paper.
