Rega is a private, non-profit
air rescue service that provides emergency medical assistance in Switzerland and Liechtenstein. It was established in 1952 by Rudolf Bucher, who believed the Swiss rescue organization needed a specialized air sub-section. This image is a
sequence photograph, stitched from 207 separate frames, of Rega's rescue helicopter
