Rithalic You could volunteer at your local RAF air cadets squadron as a civilian instructor. Was a good laugh when i did it and obviously flying related. There were two parade evenings per week (3-4 hours/night) with regular trips / events at the weekends. They only asked for as much time as i could give.
This is exactly the sort of thing I'm looking for. I have applied to the local Air Cadets squadron and am now waiting for a response. Thanks very much!
