Well, somehow a Brandy Sour tasted better in Akrotiri and a Harvey Wallbanger tasted better in the USofA.
We (OK - it was Mars Bar) once made up some pretty high octane 'Electric OJ' in the front galley of the Vickers FunBus, for dispensing to selected airshow guests at Abbotsford.
Like the 'Miss Geniality' girls and their minder (if you're reading this, Alex W, remind that old bugger Basil I still have certain photos!). But some was also offered to a visiting spam General, who happily quaffed it. "Good job the General isn't going anywhere today" said one of the VC10 crew...
"No, Sir", replied the General's bottom-wiper, "He'll be flying his C-21A back to C-Springs after the show!"
No-one dared tell him - hope he had fun flying his Lear!
The definitive PPRuNe Brandy Sour sounds as though it's almost been perfected now!
