    Very good propeller salesmen?

    “The entrance to the cockpit of this aircraft is most difficult. It should have been made impossible.” — Flight Journal magazine, April 2000, regards the XF10F-1, Grumman's first attempt at a swing wing fighter.

    Hi ccheese,

    Regarding post #4, the Ha.1109 was called the Tripala and had a Hispano Suiza engie with a 3 bladed prop. The Ha.1112 Buchon has a Merlin with a 4-bladed prop. The Spanish also addressed the Bf 109 canopy issue, at least in the 2-seat Ha.1109:

    The one shown is an Hispao Ha.1109K with HS engine and 3-blade prop.
    "Try to fly in the middle of the air. The edges can be recognized by water, ground, rocks, and interstellar space. It is much easier to not hit anything in the middle of the air than it is anywhere near the edges."

    Going to extremes this 14 blade prop arrangement maintains a 90% efficiency beyond 400 kts thanks to NASA
