First of all, many thanks to Orca for starting this wonderful thread.
Personally, I must have enjoyed my service too much as I can't think of a particular high point, but the 1st of many high points was passing out of Boy Entrant's service and arriving at my 1st flying unit.
It was BCBS RAF Lindholme where the noise of Merlin and Hercules engines was the daily soundtrack.
At a different level, watching the sunrise and sunset at Gan, from below the horizon to overhead and the reverse. Each event took just 20 minutes.
Oh Happy Daze.
