My father was M/Plt David Morton and he resigned from the R.A.F. in 1968 whilst flying Varsity and Hastings at the N.B.S. at R.A.F. Lindholme.
He went on to join S.O.A.F. flying Dakota, Skyvan, and Caribou until 1973.
He often said that M/Plt was the best rank in the R.A.F., and I think the only ground tour he had in the R.A.F. was as part of a Thor crew at Bardney, part of the Hemswell group.
I inherited his logbooks and the types he flew reads like a dream.
At least to me....
