The Besson MB.35 Passe Partout was a French two-seat spotter and observation floatplane, designed by Besson. It was intended to serve on Surcouf a very large (for its day) submarine, stowed in a sealed hangar. The first aircraft was destroyed during trials and the second was converted to the MB.41, prototype of the Besson MB.411, which did serve on Surcouf.
