Wing Commander Reginald Blayney Bulteel Colmore was the Director of Airship Development. He was born at Portsmouth in 1887 and began his career in the Royal Navy before leaving in 1911. With the onset of WW1, he was back in service in the Armoured Car Division and served at Antwerp and Gallipoli. In 1916 he transferred to the RNAS where he devised coastal defence systems against enemy submarines. His skills were quickly noticed and he was promoted to Chief Staff Officer, Aircraft Operations. After WW1 he was promoted to Squadron Leader in the RAF and was attached to the Air Ministry which inevitably led him to the R100 and R101 programmes. He was also on the successful R100 flight to Canada.
Tragically, lost his life in the loss of the R101 on 5th October 1930.
