Is it me? Why have the Fleet Air Arm started using the term "floating callsign"... as in "en-route to a floating callsign"? I know they mean a ship, and if its got radio and can accept aircraft onboard... then I'm guessing in all probabability... it's a warship.
Another Americanism I hate is using "mikes" instead of minutes e.g. "ETA 10 Mikes"
