Many, many moons ago ...
"Practice MAYDAY, Practice MAYDAY, Practice MAYDAY. London Centre this is Yeovil Flag Zero One*"
He was dealt with appropriately! and handed over to Yeovilton ATC who were informed of the initial transmission!
Yeovilton ATC rang D&D back to say that 'Yeovil Flag 01' had landed safely ... and would be buying the beer in the Wardroom that night !!!
Unfortunately D&D didn't get to taste the ale :-(
