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
Assuming re-equipping, with a reduced number of aircraft (100) through the CF-105 Arrow program, the RCAF scheduled the phasing out of its older CF 100 squadrons, less those stationed in Europe. Though, designated first to go 425 'Alouette' Squadron (St Hubert) would only be deactivated, and so 428 'Ghost' Squadron was disbanded on 31 May 1961. As the first designated CF-100 squadron to be withdrawn without re-equipping, having no WW2 fighter heritage, it was not identified to receive the new CF-105 or the used American F-101s. As a precursor to all CF-100 operational 'fighter' flying ending in December 1962, there would be no Canadian CF-105s (Feb 1959) and the alternative American F-101B Voodoo (Jul 1961) program (acquiring only 56 operational aircraft) would see five all-weather interceptor squadrons, replace the nine all-weather fighter squadrons. They were later reduced to three in 1964.
