You beat me to it
fantom!
RAF mate of mine (Andover nav) wore one and told me it was the 'ferks sake' tie. I was living in the UK at the time and never swallowed his story............until I ended up flying Skyvans for GF out of Seeb. Sure enough there was Firq and Saiq on the PDO maps we were issued with!
IIRC they were monochrome maps and we used to colour them in ourselves, with crayons, as the desert would look different at various times of the day. Talk about DIY maps. Mine was a work of art at the end but unfortunately it disappeared in one of my various housemoves.
Apols for thread drift!
