British Military Aviation in 1928

February
The Royal Air Force assumes responsibility for the defence of Aden and Royal Air Force Aden Command is formed, under the command of Group Captain W.G.S. Mitchell.

7-22 February
The first solo flight from the United Kingdom to Darwin in Australia is made by Squadron Leader Bert Hinkler, Royal Air Force (Retired), in an Avro Avian. The flight covers a distance of 11,000 miles.

21 February
Following an incursion into Aden by Yemeni forces and their occupation of the town of Dhala in late 1927, Zeidi tribesmen from Yemen invade two districts of Aden. No.8 Squadron commence operations against the Zeidi, but these are suspended after the agreement of a truce to permit negotiations between the leader of the Zeidi, the Imam Yahya of Yemen, and the British colonial administration in Yemen.

25 June
Following the breakdown of the truce between the Zeidi tribesmen and the British administration in Yemen, No.8 Squadron Royal Air Force resume bombing operations. The bombing serves both to strike at the Zeidi and to encourage tribes friendly to the British, which then attack the Zeidi. As a consequence, the Zeidi withdraw from Aden in August 1928.

28 September
The Under Secretary of State for Air, Sir Philip Sassoon, and the Director of Equipment, Air Commodore Longmore, begin a 9,900 mile flight from Felixstowe to Karachi and back, by Blackburn Iris flying boat, to inspect Royal Air Force units in Malta, Egypt and Iraq. The party returns to Felixstowe on 14 November 1928.

Following a coup by members of the Shiamwari tribe against the Amir of Afghanistan, the British Legation in the Afghan capital Kabul is isolated from the remainder of the city.
