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. 511 Squadron RAF
Formed on 14 October 1942, No. 511 Squadron was formed from No. 1425 Flight at RAF Lyneham. The squadron continued the work of the Flight operating regular transport schedules to Gibraltar using the Consolidated Liberators. To extend the route from Gibraltar to Malta the squadron also operated the Armstrong Whitworth Albemarle. As the Second World War progressed, no. 511 Squadron expanded its long-range transport role and it was the first squadron to operate the Avro York transport (A transport based on the Avro Lancaster). At first the Liberators and Yorks were operated as separate Flights, but the Liberator Flight became 246 Squadron in 1944. The squadron continued to fly trooping flights, particularly between the United Kingdom and India until the squadron was disbanded on 7 October 1946.
