The Hillson Bi-mono was a British experimental aircraft of the 1940s. It was designed to test the idea of "slip-wings", where the aircraft could take off as a biplane, jettison the upper, disposable wing, and continue flying as a monoplane. A single example was built, which successfully demonstrated jettisoning of the slip wing in flight.
