Libański Monobiplan
![]() In 1910 Edmund Libański of Lwów (then under Austrian rule, presently in Ukraine) designed an aircraft that was supposed to have advantages of both mono- and biplane through use of lift areas of different size (with upper plane much smaller than the lower one). During the take-off to first flight the engine exploded leading to crash. Designer dropped the idea of rebuilding the plane and instead designed a year later a much more succesful two-seat airplane named Jaskółka (Swallow).
