It has a retractable tricycle landing gear and the enclosed cockpit has two seats side-by-side with dual controls and a zero/zero pilot extraction system. The Stalker has two underwing hardpoints outboard of the landing gear for military ordnance.[1] The prototype was destroyed in a fatal accident on 29 May 1989.
