No. 428 Squadron RCAF
On 7 Nov 1942, he assumed command of No 428 (RCAF) Squadron, standing up the squadron in No. 4 Group. As the OC, it was noted that "Wing Commander Earle was a grand chap, one who can genuinely be called, 'One of Nature's Gentlemen'. He was well liked by the Canadians and sadly missed when he left on promotion to group captain in February 1943. He flew two operations from Dalton, occupying the astro-dome. He had previously been flying Fairey Gordons in the Middle East (Iraq), and found the Wellington difficult, partly due to his eyesight not liking the English skies, and partly as he was not a tall man." After only three months, he left 428 Bomber Squadron (RCAF) as an acting group captain on 7 Feb 1943, when he was assigned as the station commander of RAF Ridgewell and then RAF West Wickham, late in 1943, then as a temporary group captain. He ended the war as Air Officer Commanding No. 300 Group RAF (RAF Transport Command) in Australia.
RCAF Station Marville
No. 1 Wing, Canada's first NATO fighter wing, was initially located at North Luffenham, England since its French base was not ready. The first of the wing's three fighter squadrons (all squadrons flying Sabres), No. 410 Squadron, arrived at North Luffenham in November 1951. The squadron and its aircraft, along with those of No. 441 Squadron, were ferried across the Atlantic to Glasgow, Scotland aboard . The personnel of 441 arrived by ocean liner in February 1952. In May–June 1952, No. 439 Squadron flew from RCAF Station Uplands via Bagotville, Goose Bay, Greenland, Iceland and Scotland, in an exercise known as "Operation Leapfrog."
