Abstract: The file contains correspondence and notes related to air facilities required by Imperial Airways (from 1940 the British Overseas Airways Corporation - BOAC) and the Royal Air Force (RAF) along the Arabian Coast. The file therefore contains a number of lists (some of which are categorised by priority) prepared by the Air Ministry outlining British requirements for navigation beacons, wireless transmissions sets, direction finding sets, moorings for flying boats etc; the lists prepared by the Air Ministry are revised over time to reflect changing requirements, for example the introduction of night flying. Also covered in the file is the establishment of a petrol dhow at Dubai in 1934 (see folio 402 for a copy of the agreement), and consideration in 1938 of arrangements for the provision of fuel at Ras al Khaimah [Ra's al-Khaymah] for Imperial Airways in cases of emergency.Another topic featured in the file is the introduction of a flying boat service by Imperial Airways in 1937, and the selection of a suitable stopping point along the Arabian Coast. The selection process is covered, which includes consideration of Dubai (also spelt Debai and Dabai), Ras al Khaimah, and Umm al Qaiwain [Umm al-Qaywayn] as potential sites. This process culminates in the Dubai Commercial Air Agreement (1937): see folios 223-226 for a copy of the agreement with both Arabic and English translation. This includes an agreement respecting security arrangements for passengers transferred between the alighting area at Dubai and their accommodation at Sharjah: see folio 199 for an English translation of the agreement. Further correspondence relating to its renewal in 1943 can also be found in the file. The prospects for the future use of Dubai and Sharjah, as of 1946, are also briefly discussed at the end of the correspondence.Material related to a survey of Sharjah Creek in 1939 and Dubai Creek by Bernard Whitteron in 1941 can be found between folios 36-57. This includes sketch maps the two creeks: Dubai (folio 48) and Sharjah (folios 53, and 55-56). It has been included in consideration of possible engineering work to enhance their navigability and hence their utility for flying boats.The main correspondents are as follows: the Political Resident in the Persian Gulf, the Political Agent at Bahrain (Tom Hickinbotham, Hugh Weightman, and Reginald George Alban), officials of the Air Ministry, and officials of the India Office.The file includes a divider which gives a list of correspondence references contained in the file by year. This is placed at the back of the correspondence.Physical description: Foliation: the foliation sequence for this description commences at the inside front cover with 1, and terminates at the last folio with 466; these numbers are written in pencil, are circled, and are located in the top right corner of the recto side of each folio.
