Hi
The only reference I have come across is from ‘The Royal Navy’s Air Service in the Great War’ by David Hobbs, page 295, where, reference Dunning, it mentions that:
“On 12 December 1916 he was appointed to the Admiralty for ‘B’ Section of the Air Department which was looking into ways of operating wheeled aircraft from ships and in the early weeks of 1917 he is known to have carried out deck landings on the dummy deck at Isle of Grain in Sopwith Pup 9497, …”
I presume this ‘B’ Section was a sub-unit as it does not appear to be included in lists of units that were based at Isle of Grain during WW1, which also appear to have had frequent ‘name changes’.
