These were retired a few years ago but until then, if you were in trouble on a mountain or at sea this is the sight you wanted to see. This example is now flown by Historic Helicopters based at Chard in Somerset. Photographed at the Shuttleworth Collection's Family Airshow in Bedfordshire 2021. Until I tried I thought helicopters in flight would be easy to photograph, however because the rotor speed is relatively low it is very easy to freeze it. This is shot at 1/100s.
