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. 428 Squadron RCAF
Tiger Force's No. 6 Group, RCAF / No. 661 (Heavy Bomber) Wing (10 July 1945), to be commanded by Wing Commander F.R. Sharp, DFC, was to form at RCAF Station Yarmouth, Nova Scotia with No. 419 and No. 428 Squadrons. Beginning reorganization and training on 10 August 1945 'Ghost' Squadron was to be ready for deployment on 1 January 1946, manned with ‘volunteering' personnel from within No. 6 Bomber Group. The 'volunteers' would be sought amongst those who had not served overseas, those who had not yet completed their tours, in sorties or hours and actually elected to participate. Their Mk. Xs were to be modified, removing the mid-upper turret and fitting huge "saddle tanks" on top of the fuselage, painted and crewed for an initial six week training programme flying from Yarmouth. With the bombing of Hiroshima and Nagasaki (06/9 August), and Japan's formal surrender on 2 September, No. 428 Squadron received disbandment orders on 5 September 1945.
