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. 414 Squadron RCAF
The squadron then reformed on 15 September 1967 at RCAF Station St Hubert in its new role as an electronic warfare squadron flying the CF-100. In August 1972 the squadron moved to CFB North Bay where it remained for the next twenty years flying the CF-100, CC-117 and EF-101. In 1992 the squadron was split into two parts with one part going to CFB Comox as No 414 Composite Squadron and the other part going to CFB Greenwood as 434 Composite Squadron. In 1993 the squadron changed its name to No 414 Combat Support Squadron when it was equipped with the CT-133 Silver Star. The Squadron was disbanded in 2002 when its duties were contracted out to a civilian company.
