Passage:A military flying school was set up at the site of the present-day RAAF base on 28August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30June 1925 as the fledgling service's first air base outside Victoria. Its initial flying unit was No.3 (Army Cooperation) Squadron, operating Airco DH.9 light bombers and Royal Aircraft Factory S.E.5 fighters, and for the next decade the commanding officer of No.3 Squadron was also in charge of the base. Among these were Squadron Leaders Frank Lukis (192530), Harry Cobby (193031), and Bill Bostock (193133). Headquarters RAAF Station Richmond was formed as a separate entity on 20April 1936, under the command of Group Captain Adrian "King" Cole. Other units, including No.22 Squadron flying Hawker Demons, and No.2 Aircraft Depot, had been established in the preceding months. No.4 (General Reconnaissance) Squadron was formed in May 1937, followed by No.6 (General Reconnaissance) Squadron in March 1939. Two Fleet Cooperation units were also established, No.5 Squadron in April 1936 and No.9 Squadron in January 1939. No.23 (General Purpose) Squadron formed in February 1939. As well as an Air Force base, in its pre-war days Richmond was used as a supplementary airport for Sydney; various aviation pioneers employed it in the 1930s, including Charles Kingsford Smith and Jean Batten.

Input: Consider Input: Question: Was the king that Greaves served as travelling physician related to Charles I? Passage:Charles I is supposed to have created him a baronet 4 May 1645. Of this creation, the first of a physician to that rank, no record exists, but the accurate Le Neve did not doubt the fact, and explained the absence of enrolment. He claimed to have been Physician-General to the army of Charles I. With his friend Walter Charleton, Greaves became travelling physician to Charles II, but settled in London in 1653, and was admitted a fellow of the College of Physicians 18 October 1657. He delivered the Harveian oration at the College of Physicians 25 July 1661 (London, 1667, 4to), of which the original manuscript is in the British Museum (Sloane 302). He says that before Harvey the source of the circulation was as unknown as that of the Nile, and compares England to a heart, whence the knowledge of the circulation was driven forth to other lands. He became physician in ordinary to Charles II, and owned the lands of St Leonard's Forest in Sussex, including that part which became Leonardslee. He married Alicia Nevett (16241684), widow of Peter Calf (d. 1668). Greaves lived in Covent Garden, died there 11 Nov. 1680, and was buried in the church of St. Paul's, Covent Garden.
