Question: How old was Adrian "King" Cole the year that headquarters RAAF Station Richmond was formed as a separate entity? Passage 1:The Indian Squads were announced on 13 February. Dhawal Kulkarni got his maiden call up to the national squad, having been selected for the test squad after a strong debut Ranji trophy season where he was the highest wicket taker. L Balaji made a return to the Test squad after a five-year hiatus having last played in a test in 2004. Balaji was dropped from the ODI squad after he played in a single match in the previous tour, he was replaced by the now fit Munaf Patel. In the test squad Balaji replaced Pragyan Ojha with the selectors opting for an extra seamer instead of an extra spinner for the tour. Ojha retained his place in the ODI and T20 squads. Subramaniam Badrinath was dropped from the test squad in favour of reserve Wicket-Keeper Dinesh Karthik after Karthik too had a strong Ranji trophy season. Karthik was selected for all three squads, replacing Jadeja in the ODI squad. Ravindra Jadeja's impressive ODI debut was rewarded with a call up to the Twenty20 squad but Jadeja will be replaced by Sachin Tendulkar for the subsequent ODI series. Munaf Patel made a return to all three squads after having to pull out midway through the previous tour of Sri Lanka due to injury. Harbhajan Singh also made a return to all three squads after having to pull out at the beginning of the previous tour to Sri Lanka due to injury.
 Passage 2:A military flying school was set up at the site of the present-day RAAF base on 28 August 1916, when the area was known as Ham Common. RAAF Station Richmond was established on 30 June 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 (1925–30), Harry Cobby (1930–31), and Bill Bostock (1931–33). Headquarters RAAF Station Richmond was formed as a separate entity on 20 April 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.
