Switzerland. Canton Ticino. Blenio Valley. View on the snowy Alps from a Rega Agusta A109 SP Grand "Da Vinci" helicopter on a rescue mission. The name Rega was created by combining letters from the name "Swiss Air Rescue Guard" as it was written in German (Schweizerische Rettungsflugwacht), French (Garde Aérienne Suisse de Sauvetage), and Italian (Guardia Aerea Svizzera di Soccorso). Rega is a private, non-profit air rescue service that provides emergency medical assistance in Switzerland. Rega mainly assists with mountain rescues, though it will also operate in other terrains when needed, most notably during life-threatening emergencies. 10.09.2017 © 2017 Didier Ruef
