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.
435 Transport and Rescue Squadron
No. 435 Squadron RCAF was formed on 1 November 1944 in Gujarat, India during the Burma Campaign, flying the Douglas Dakota in support of the Fourteenth Army. After war's end, the unit was relocated to England, where it provided transport to Canadian Army units in Europe. Deactivated on 1 April 1946 in England and re-activated three months later at RCAF Station Edmonton, the squadron relocated a few miles north to RCAF Station Namao in 1955, flying the Fairchild C-119 Flying Boxcar.
