Designed by Piet Alsema the Sagitta first flew in 1961, after three years of planning. It has an all-wood fuselage and wooden wings with fabric cover. The Sagitta was the first "standard class" glider design to appear from the Netherlands. It was a modern high performance design with features like automatic connecting control surfaces on assembly and a backward sliding canopy that can be fixed open in flight at several positions.
Of the 21 Sagitta's ever built, there are only 5 left flying. [1]
