 Wittman developed the C-85 powered "Flying Carpet" in 1953, later renaming it to the "Tailwind".In 1953, the Tailwind became the first aircraft covered under the FAA's Experimental category to be certified to carry a passenger.While crude looking by modern standards, it outperformed many similar factory-built planes, and only with the advent of composite construction were new designs able to achieve similar speed per horsepower and range.
