The Alouette II (Lark) was the first turbine-powered helicopter in the world to go into production.
On March 12, 1955, the prototype SE 3130 made its maiden flight; Within three months, on June 6th, an Alouette II flown by Jean Boulet set a new height record for helicopters of 8,209 m (26,932 ft) in preproduction. According to the manufacturer, such early demonstrations of the Alouette II had helped promote the performance and advantages of turbine helicopters over their piston-engine counterparts. The first series Alouette II was completed in April 1956. This makes it the first series helicopter with a turbine drive worldwide.
