A 're-engagement' suggestion
How about this for an idea, and apologies if it is already happening.
Each ATC squadron does a class based lesson on HLS selection. They then identify suitable local sites. Ask the landowners permission. Carry out a site survey.
All the site details, timings of parade nights and contact details are fed into the system.
As part of the rotary training program, crews are encouraged to visit as many ATC squadrons as the sortie permits. Even if it is just a 'touch and go' whilst being 'marshalled' by a cadet.
At least this way, cadets will get a look at the aircraft, even if they can't fly in them.
They could even dispatch an aircraft once a week solely for this purpose. I bet you could 'touch and go' 10 sqns in a 2 hour trip.
