Shawbury in the early 90s was always a good happy hour - loads of air traffickers to bait and pilots from so many different helo Sqns there was always harsh banter to be had. One particular night the window was very busy - it started with an Act Plt Off and saw every rank through to and including Air Cdre.
Champagne breakfasts at CFSH always had to finish up in happy hour - although it took the normal happy hourers a little while to catch up!
