Just for info there are 10 MD 902s in use by the Emergency Services in UK.
5 are dedicated police units, 2 are joint Police / HEMS units and 3 are dedicated HEMS units. As far as I know there are no firm orders for any more at this stage but possibly 1 police and 2 HEMS units are very keen to purchase.
The biggest problem is the price difference between the 135 and the 902 as they are both good aircraft.
