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.
RCAF Station Grostenquin
All twelve Air Division squadrons flew the Canadair F-86 Sabre day fighter. The squadrons originally based at Grostenquin were 416, 421 and 430. Beginning in 1956 four all-weather CF-100 squadrons entered service with Air Division. One squadron in each wing was replaced by a CF-100 squadron. No. 416 Squadron was replaced by 423 Squadron at 2 Wing. In 1959 Canada adopted a controversial nuclear strike role in accordance with NATO's doctrine of "limited nuclear warfare" and began re-equipping with the new CF-104 Starfighter that could deliver nuclear weapons. This aircraft also had a reconnaissance role. In the fall of 1962 the Sabre squadrons of the Air Division, including 421 and 430 Squadrons at 2 Wing, were re-equipped with the Starfighter. Concurrently, CF-100s ceased operation in the Air Division and 423 Squadron was disbanded.
