Beechcraft Model 17 Staggerwing first flew in 1932. It flew air races, served in WW2, and served as a civilian transport. One of its rare features is the lower wing being ahead of the top wing.


  The Model 17's unusual negative stagger wing configuration (the upper wing staggered behind the lower) and unique shape maximized pilot visibility while negligibly reducing interference between the wings.
