Shape for a kite or other surface used in flight.

The kite herein shown as embodying my invention, comprises a surface or surfaces of air resisting sheet material 1 of silk or other suitable material having the general form of the frustum of a pyramid. The term "pyramid" is here used in its generic sense and includes not only a frusto-conical form but also all irregular as well as regular frusto-pyramidal forms.

The angles of the surfaces are said to exert a stabilizing effect.
