Abstract: A flight training assembly is disclosed comprising an airplane having pilot operable flight controls, a truck for propelling the airplane at a speed sufficient to achieve lift of the airplane, and a boom structure interconnecting the airplane and truck. One end of the boom is interconnected with the truck for pivotal movement relative thereto about horizontal and vertical axes, and the other end of the boom is interconnected with the airplane at the center of gravity thereof by means of a spherical bearing assembly. Pivotal movements of the airplane relative to the boom and of the boom relative to the truck are limited.

Abstract: A hang glider in the form of an aerial wing of airfoil shape is disclosed. The wing is defined by an outer envelope of flexible material inflatable to the airfoil shape and having a plurality of chambers therein each receiving an inflatable bladder. Air inlet openings are provided in the bottom portion of the envelope adjacent the leading edge of the wing. Either the bladders or the chambers are inflated with a gas lighter than air and, during flight, air enters the openings and fills the available space in the others of the bladders or chambers to provide a complete smooth airfoil shape for the wing. Shroud lines are employed to suspend a person beneath the wing during flight.
