Hi Nick

I need to be very carefull here !
Gash in modern British language, in some parts of the Uk such as the west country stands for that one certain part of the female body we are all glad they have.
So putting that into the circumstance you have mentioned it will work but, sounds wrong for the period to me, though i would imagine the average fighter pilot was more than capable of many a good swear word?

Hope this helps a bit

Jon
