New Italian Airplane for High Speed is a Flying Tunnel
THIS odd machine, the Stipa-Caproni, which has just been completed in Italy, and has passed severe tests, is expected to be the type of future record-breakers.

The propeller, it will be seen, is located in a cylinder, through which the air-stream is driven. This “Venturi tube,” all of wood, concentrates the pressure.

The span of the model shown is 50 feet; pilot and passenger occupy a stream-lined cabin above the tunnel-shaped body, which the wing bisects.
