 Both the single Aiguillon and Arbalète airframes survive and are on public display at the Flieger-Flab-Museum, Dübendorf; the glider test aircraft was destroyed in an accident.The aircraft was to be powered by four turbofan engines buried in the wings, with the bypass air feeding cold-air pipes each side of the engines, being routed through a combustion chamber where additional fuel could be burned as a form of reheat, or deflected though large slots on the upper and lower wings to act as aerodynamic flaps or thrust reversers.Two engines could be shut down in flight to increase range.
