BOAC and teeteringhead
Monkton Combe, 9th May 1980 (so not the 70's - sorry). I'm looking at the photos now and they're definitely Hawks.
Story goes that a visiting brass - dropping in to take the salute at the annual CCF parade - said to one of the Masters as he left: "If there's anything I can do for you, do ask..."
Said Master cheekily asked for the Red Arrows.
A few months later, we were suddenly turfed out of lessons and herded up the hill for what we presume was a pre-season practice session. Glorious.
If anyone up there on the day (or perhaps I should say "down there" on the day) is out there - thank you. You made 325 young men and women very happy - a rather deaf !
