Burns, Sam / Burns Aircraft Co BA-42
Burns Aircraft Co began development in 1964 of high-performance 6/8-seat business aircraft powered by two Continental flat-six engines. The prototype Burns BA-42 flew for the first time on 28 April 1966.
It was claimed that the Burns, thanks to superior aerodynamic refinement, would do on two 210-hp engines anything the Cessna 310 would do on two 260s. On closer examination, you discovered that when the Burns' lighter weight and lower payload were taken into account, it would not.
