Well here we go again....
The PSNI helicopter must have the highest utilisation rate of any in the UK with those hours. Now, I suggest you use your well exercised skills of FOI requests to find out the annual hours for the air ambulance cabs. You might be surprised.
Perhaps your knowledge and perception could help you campaign for a full time dedicated air ambulance for the province instead of a committee designed camel which wouldn't help either organisation. One which flies for 24 hours a day, with huge fuel tanks, small land anywhere size, all weather day/night/fog capability, flown and crewed by robots who never sleep, eat or need an outside life, never needs maintenance, cheap to buy and run, and while we're at it could you arrange for all accidents to happen one after the other and nicely spaced so there is no idle time or transit distances to mess up the statistics.
