No idea if it flew or not.
Your post prompted me to research this. This is in the Hiller Aviation Museum. I never heard of it but its quite a place. I looked at a ton of photos of their exhibits. Your picture is actually of the 1911 Evergreen glider. It flew, but briefly, killing the inventor a Mr Montgomery on its test flight. The exhibit sits right alongside of the one for the 1908 Aerocycloid, A real contraption attempting vertical flight. I'm sure that didn't fly. Thanks for an interesting morning, Littleowl. I had fun trying to track this down. Not picking at your post. You just picked up the sign from the adjacent exhibit.
