If you are willing to commit and put the effort in then the RAFs Volunteer Gliding Squadrons (VGS) are always looking for staff who have the right attitude.
Volunteer Gliding Squadron - Wikipedia, the free encyclopedia
You will be expected to help out on the airfield and may find you work more than you fly (helping to launch gliders, retrieving gliders or operating the winch), but you will fly. The social side of it is really good, it is a real team effort. There are lots of younger staff, a constant supply of cadets from the Air Training Corps who complete their training and stay on as flight staff cadets before becoming civilian instructors.
Find a squadron close to you and give the Officer Commanding and phone call, they usually only operate at weekends though.
