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. 21 Squadron RAAF
No. 21 Squadron is a Royal Australian Air Force (RAAF) general reserve squadron. Formed in the mid-1930s as a unit of the part-time Citizen Air Force (CAF), it was mobilised for service during World War II, when it saw action against the Japanese as a fighter unit in the Malayan campaign, a dive bomber unit in the New Guinea campaign, and a heavy bomber unit in the Borneo campaign. After the war, the squadron continued to fly until 1960, when the CAF ceased flying operations. At that time, No. 21 Squadron converted to a non-flying support role, which it currently fulfils at RAAF Williams.
No. 21 Squadron was formed at RAAF Station Laverton on 21 April 1936, as a Citizen Air Force (reserve) squadron. Under the command of Squadron Leader J.H. Summers, the squadron had a cadre of regular RAAF personnel who served alongside the part-time members of the CAF and initially operated a variety of aircraft including Hawker Demons, Westland Wapitis and de Havilland Gipsy Moths. With these aircraft, the squadron undertook several tasks. As a CAF squadron, training was its main role; its personnel were instructed in fighter tactics, bombing and army co-operation duties; they were also used for search-and-rescue tasks and public relations duties. The squadron also received Avro Ansons and Bristol Bulldogs in late 1936 and early 1937. In May 1937, Charles Eaton took over as squadron commander.
