Just to take this way off thread for a second, there was talk a few years ago of some of the larger UK fire brigades looking to develop a helo support capability for airborne spotting/control & metro SAR/CASEVAC.
Would/Could a national air support organisation go some way into being able to provide greater capability in this way by having a selection of airframes/roles that could be called upon by a range of organisations - eg police/fire/ambulance and therefore be funded centrally?
