Nice to see Halton put to such use. I've personally given many youngsters (mostly ATC/CCF cadets) their first flights in gliders and microlights there.
Years ago when Roger Dixon was OC Airfield I was flying with the Ridgerunners Microlight Club (no relation to RAF Halton Microlight Club) and he talked me into 'controlling' the Air Squadron Trophy day; 19 aircraft and about 150 movements in about 3 hours!
