Isnt that the domain of Air Transport Auxiliary Air Transport Auxiliary - Wikipedia By 1 May 1940 the ATA had taken over transporting all military aircraft from factories to maintenance units to have guns and accessories installed. On 1 August 1941 the ATA took over all ferrying jobs. I find it difficult to see why in the early 1940's a 40 year old railway clerk would be used to fly aircraft on non operational sorties when you have all those ATA ladies. I have nothing against Railway Clerks but they were often a reserved occupation [as my grandfather was in WW1] to ensure the smooth running of the trains TD
The ATA had both men and women, it is a common misconception that women only were employed. At 40 yrs old maybe he failed the military medical but if he had a pilots licence then was suitably employed
In my post I said he could have been ATA and in your link it states 1943 women received the same pay as their male co-workers
This was the official figures and men greatly outnumber the ladies but since 1990 you only hear about the ATA ladies
States Battle of Britain flying when pilot numbers were down and flying over Germany Without further info this is all guesswork on something that actually happened or a complete family urban myth. So further in put required from family to get it back on track
