Having been involved with group aircraft for 28 years shared ownership is firmly supported here.
PFA permit types and privately owned (non public transport) group shares are welcome to be posted here by those involved with a group, as are PPRuNers offering hints, tips and experiences.
Just the search for a share often opens up an entirely new world of aviation in the UK for those who have come through the standard club/school world. Enthusiasm and interest seems to be retained far longer through this route than any other. We are also very keen on the gliding days for the same reason - an aviation community generally far removed from commercial club life.
Positively encouraged and supported here at the Towers.
