What would you do if it was a heli? Join the tips of the rotors?! :P

With intermeshing rotors, all is possible, side by side... :)  :wacko:

According to "Le Trait d'Union" magazine (French branch of Air Britain) #213, the Hanriot HD-141 was a 1929 conversion of 4 HD-14, 4 HD-32, 4 HD-321.
According to http://www.aviafrance.com/aviafrance1.php?ID=5677 this Hanriot HD-141 was built in 10 copies, including 8 from HD-321.
As it seems there is no HD-141 picture available anywhere, I am proud to present the very first one, the asymmetric HD-141HB Hémi-Biplan: half-biplane (biplane on starboard, no wing on port) but not monoplane. Why?! How?! Well, this was due to the incredibly powerful engine (130hp officially, maybe 180hp secretly!!!) providing a huge torque that needed counter-balance by lift on a single side.

And at http://www.secretprojects.co.uk/forum/ , our dear Overscan mentioned a Blackburn P.141 looking like a Phantom…
