The Swiss Air Force Alouette III light helicopter took to the skies for the final time with a formation flight over its home base at Alpnach, Switzerland, after 46 years of service and 300,000 flight hours.

The Alouette III is a single-engine, light utility helicopter developed by Sud Aviation and later manufactured by Aérospatiale of France.

Originally powered by a Turbomeca Artouste IIIB turboshaft engine, the Alouette III is recognised for its mountain rescue capabilities and adaptability.

Apart from the significant role of helicopter pilot training, Alouette IIIs were used in other roles including fire fighting and disaster relief.

The type has been replaced by Eurocopter’s EC635, according to Shephard Group.
