Abstract: The file is concerned with proposals for the construction of an airfield – suitable for very heavy bombers – at Dhahran by the United States Army Air Transport Command as a wartime necessity, and applications from the United States to the United Kingdom for the latters support in obtaining permission from Saudi Arabia. See folios 239-241 for a brief on these proposals.The file also contains papers related to proposals for the post-war civil operation following the construction of the airfield, and the transfer of ownership from the United States to Saudi Arabia. Related papers concern proposals from Trans World Airlines for the development of civil aviation in Saudi Arabia, and counter proposals from the British Government for a civil air mission. This includes the use of Dhahran by the British Overseas Airways Corporation (BOAC).A typed copy of a report by a Ministry of Civil Aviation Technical Survey Party on aerodromes in the Middle East and Persian Gulf (1947) has also been included: see folios 26-55. The minutes of a subsequent meeting held by the Civil Aviation Planning Committee on 1 April 1947 to discuss the reports findings can be found on folios 18-19.The main correspondents in the file are as follows: HM Minister at Jeddah (Sir Laurence Grafftey-Smith), officials of the Foreign Office, officials of the Ministry of Civil Aviation, and officials of the India Office (Commonwealth Relations Office from August 1947).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 (used for referencing) commences at the inside front cover with 1, and terminates at the last folio with 260; these numbers are written in pencil, are circled, and are located in the top right corner of the recto side of each folio.A previous foliation sequence, which is also circled, has been superseded and therefore crossed out.
