On 13 May 1912, with the establishment of the Royal Flying Corps, No. 1 Company of the Air Battalion was redesignated No. 1 Squadron, Royal Flying Corps. No. 1 Squadron was one of the original three Royal Flying Corps squadrons. Maitland continued as the new squadron's Officer Commanding and he was promoted to major several days after the establishment of the squadron. It retained the airships "Beta" and "Gamma", adding "Delta" and "Eta", as well as kites and a few spherical balloons. However, in October 1913 a sudden decision was made to transfer all the airships to the Naval Wing of the RFC (which became the Royal Naval Air Service by Admiralty dictat, not Cabinet decision, on 1 July 1914). While retaining kites 1 Squadron was reorganised as an 'aircraft park' for the British Expeditionary Force.
