    “Without a propeller”!? When have you ever been able to see a propeller on a flying aircraft??

      All the time, the tip has to stay subsonic so they don’t spin that fast. 1021 RPM on an H-model herc for example.

        Huh, interesting. It just seems like from a distance, while both it and the aircraft are moving fast, a visual determination of whether a propeller is there or not or not seems… difficult.
