Thomas-Morse S-9
The 1923 Thomas-Morse S-9 Army trainer was a widened side-by-side cockpit in an all-metal corrugated fuselage, with wings from S-6 and tail from S-4C.
Only one was built but during Army flight tests at Kelly Field TX, it showed structural problems and the pilot bailed out; however, the plane reportedly glided to an "almost-successful landing" except for losing its wings when it went between two trees. It was sent back to Thomas-Morse, but never repaired.
