6 AEF at Benson have had RAF, Army and Navy pilots on strength. My understanding is that, in normal circumstances, AEF pilots must be service trained. there may well be exceptional cases. Those that are no longer in the services take a commission as VRT officers. Those still in fly as they are. Haven't come across an Army Non-Com but I expect he, or she, ( havent met one of those either), would be welcome.
The VGS pilots need to be PPLs at least, with a certain amount of experience, and go through training at Syerston.
