A. de la Hault is the one second from right!
And not wondering !
The man into white skirt total left is nonelse than Henri Villard!
Question is now, who was the man behind the conception of this flapwing plane ...de la Hault or Villard?
Here a third one published into a German bookwork 1910
Thinks the name is "Collomb" and Frenchman?
Kimbal was wrong indeed in this way as that was a plane with 24 propellors to try lift it less or more vertically too!
That's much ore a kind of precedessor into helicopter history!
