here is a USA airplane Project ...

This is a notional design. The article doesn't specifically state that the concept came from the US. It just says that the design issue of visibility " is already solved with excellent results in Italy and the United States."

Thank you my dear Apophenia for the explanation.

Dozens of engineers have speculated bout central propellers.These days you can count the number of successful central propellers on one finger .... and that is on a low-speed, European-built auto-gyro.
