  • Patent number: 4012865
    Abstract: A toy airplane of foldable sheet material which is constructed to glide through the air with a horizontal velocity component after being released in the air above a predetermined starting velocity. A wing and body section of the airplane may be constructed of two separate sheets of foldable sheet material, with one of the sheets forming a substantial part of the body section extending through a slot in the other sheet which forms a substantial portion of the wing section. The sheets forming the wing and body sections are clamped in position with respect to one another by paper staples extending through the sheets. One preferred embodiment of the airplane includes a launching hook securely attached to the sheets forming the wing and body section, which launching hook is also formed of a sheet of foldable sheet material clamped into position by the staples connecting the wing and body sections to one another.
