It is a BD 4 that he built and never took off Captiva Island. It has never flown, and may not be complete, just looks finished from the outside. Few people would be willing to risk test flying such a plane, especially after sitting in the sun for years. I am afraid that a lawn ornament is the best future for this individual plane.
I wonder how many BD 4's there are currently in airworthy condition? I have never even seen one, unfinished or finished.
A high school friend built such a plane,a half Volkswagen powered biplane, and after some taxi tests, chickened out and never flew it. He taxied it in Fourth of July parades until the fabric started to tear. He had decided it was not properly assembled, and not safe to fly. His judgement is better than mine, so I did not try to change his mind, especially since the fabric had tears from the sun damage. I might add that I did not remember that he was much of a mechanic when we were in our teens.
