I well remember the RAF white glove/green glove/white glove fiasco. Every crewmember in the RAF got new green gloves, only to be given brand new white ones some monthe later. In the finest tradition of the RAF, our Sqdn opted to wear one of each until some months later an order was issued to tell us to desist. I still have the green pair somewhere. As for improving your flying abilities, never in a few thousand flying hours did it make one iota of difference. With or without, rather than white over green!
