Wee Jock, was your F4 pin made out of an old Penny by a guy at Wainfleet?
The closest I got to an airborne toom was at Wainfleet when 78TFS used to do their range clear flypasts to check for hung ordnance. We used stand on the balcony of the old tower at approx 35 Feet AGL and try to check the underside of the aircraft.
We never did see the underside as they used to scream past at 420kts at the same level as us with the Pilot and WSO waving frantically.
Spent 3 Years at CGY having a ball, used to love working nights in the tower watching burner take-offs and nipping out to the caravan to watch cable engagements.
