  • Project Quicksilver in Hang gliding before 1973. Although not strictly a flex-wing in that any change in geometry of the wing in flight had no direct bearing on its flying characteristics, the Quicksilver was built using contemporary flex-wing hang glider technology.

  • Luff in the time of cholera for the simplest of all tails; the sailfeather
