This is incorrect - all Cierva and Cierva-licensed machines were called Autogiros, a term Cierva patented (copyrighted) - all non-Cierva licensed machines (example TsAGI A-7) or those based on different technologies (example Wilford Gyroplane or Herrick Convertiplane) are autogyros. 10/04/2002 @ 18:32 [ref: 5812]
