T'aint Natural,
The AAC used to help with environmental work in the Snowdonia national park. They used to ferry large amounts of stone, used for repairing footpaths, as underslung loads. This was good training for the crews and appreciated by the locals who got the paths repaired and nobody complained about the noise. Some commercial operators, however, complained that the military were stealing thier work. In the interest of fairness, it was decided that the military should charge for the service and, thanks to some short sighted bean counting in the corridors of Whitehall, priced themselves out of a superb training opportunity.
As for air ambulance work, could you actually get anyone other than military personnel to fly in a Lynx? The aircraft cannot meet any of the group 'A' or public transport requirements. No prizes for guessing what the CAA would make of the idea.
