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 plywood
and 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. Design errors (selection
of wingtip airfoil and 'delamination' of the main spar) resulted in
some accidents.
Of the 21 Sagitta's ever built, there are only 5
left flying. [1864]
