The Sorensen BF9-2 is a one-off custom biplane, designed and built by Danny specifically for airshow flying. Construction time alone consumed nearly 6,000 man-hours of labor, not including design time. It features 1930's styling with modern day high performance. It is powered by a 360HP Vendenyev M14-P 9-cylinder radial engine turning a three-blade MTV-9 propeller of 8-1/2 foot diameter. This combination produces a static thrust of more than 1,600 lbs. "Unfinished Business" carries the registration number N81973, the same number that was on the airplane in which Danny learned to fly. The BF9-2 truly has an international heritage: The engine is Russian, the propeller is German, the brace wires are Scottish, the airframe is American, and the pitot tube is from a North American F-86 fighter jet!
