The Morane-Saulnier MS.250 was a crew-trainer aircraft built by Morane-Saulnier in the late 1920s.

Design

The MS.250 was a parasol-wing monoplane with swept-back wings, similar to the Morane-Saulnier MS.230, but differed in having a new tail. The cockpits had windscreens, and the rear cockpit had a gun ring. The pilot-instructor manned the front cockpit, and the trainee observer manned the rear cockpit.[1] A second aircraft was built with a more powerful engine as the MS.251.[2]
