(This features wheels and so forth, but also smooth brakes along the lines of a pressed-down ski, making use of Esnault-Pelterie's familiar hydropneumatics pistons. All told, between the smoothness and "elasticity" offered by these brakes, and the frame flexibility offered in the second certificate of addition, Esnault-Pelterie offers here a well-considered and gracefully durable aircraft.)
