Ind Coope/Allied Breweries had their own fleet and their own airfield too - Tatenhill near Burton On Trent (unsurprisingly). Not sure if they owned Tatenhill outright, but at the time they were pretty much the only activity there - around late 70's possibly early 80's.
My Dad Worked for Ind Coope and I remember as a young boy us regularly dropping him off at the airfield to head off (as a pax, not pilot) to tropical paradises such as Southend and Lossiemouth!
