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.
No. 6 Squadron RCAF
On 12 March 1945, the Canso crew of Flight Lieutenant Moodie sighted a partially deflated Japanese fire balloon over Rupert Inlet, and forced it down on the south side of Rupert Arm by flying above it. The balloon was subsequently recovered by a ground party and sent to Western Air Command headquarters for inspection. As the war drew to a close, the squadron was disbanded on 7 August after flying its last patrol on 1 August. The squadron flew 2,506 sorties during the war, and had a total of 11,716 operational flying hours and 10,565 non-operational flying hours. Its only losses were two aircraft and nine aircrew killed in non-operational incidents. None of its personnel received decorations. It earned the battle honour Pacific Coast 1941-1945, but was never awarded it due to its disbandment.
