The Timm Aircoach, also called the Timm Coach and the Golden Shell Special, was a custom-built, high-capacity, high altitude aircraft for charter flights.[2]
Design and development
The Aircoach was built in a shop at Glendale Airport, where Otto and Wally Timm had a shop. Al Menasco had a shop nearby where he modified engines. The Aircoach used a Menaso modified Salmson engine.
The Aircoach was a single engine, conventional landing gear equipped biplane with an open cockpit for two pilots and enclosed passenger cabin. The fuselage was made of welded steel tubing with plywood covering.[3]
Operational history
Roscoe Turner flew the underpowered Shell Special Golden Shell twice, attempting endurance records. Each flight resulted in damage and the efforts were abandoned.[3]
