I posted this many years ago and in the circumstances thought it worth reposting.
Duke of Edinburgh’s R.A.F. Commission
On January 15th [1953] the Air Ministry announced that Her Majesty the Queen had been graciously pleased to appoint H.R.H. the Duke of Edinburgh to a commission in the Royal Air Force, in the rank of Marshal of the Royal Air Force, with effect from that date. Simultaneous announcements by the Admiralty and War Office gave news, respectively, of the Duke’s promotion to ranks of Admiral of the Fleet (he is already a commander in the Royal Navy) and of Field Marshal.
The Duke, who recently succeeded the late King as Air Commodore-in-Chief of the Air Training Corps, now becomes the third member of the Royal Family to have held the highest rank in the R.A.F. King George V did not hold the rank as such, but assumed the title of Chief of the Royal Air Force. The Duke of Windsor was appointed a Marshal of the Royal Air Force on his accession in 1936 and has retained that rank since his abdication, and the late King George VI also assumed the rank on his accession. Both the Duke of Windsor and King George VI learned to fly, the former being taught by A. Cdre. Sir Edward Fielden and the latter by Air Chief Marshal Sir Alec Coryton.
..and here he is flying over his home in a 'five star' Harvard.
