Flying Ambulance

I've seen helicopters take off an land quite a few times as I've cycled along University Boulevard, but this is the first time that I have managed to capture one stationary. They use a sports field as a sort of heliport, which is good for this air ambulance, as the Queen's Medical Centre is only a short drive away, so the patient could be getting the care they need in only a few minutes. I'm not entirely sure why this particular helicopter belonging to Derbyshire, Leicestershire and Rutland is there, as Nottinghamshire and Lincolnshire have their own. But maybe they share the same ground.
