ABSTRACT:
A one-piece, model glider craft capable of sustained flight in a glider mode in both atmospheric and underwater conditions. The glider craft comprises a delta wing structure including right and left wing sections which diverge rearward on opposite sides of a central axis from a single, forward most wing edge. A continuous leading edge extends across the front of the glider craft along the forward edge of the right wing, across the forward most wing edge and across the left leading wing edge. An elongated central body projects upward from a top surface of the delta wing structure along the central axis and is configured to provide a balanced distribution of weight. A tail fin or other vertical stabilizing structures attached at the rear part of the glider craft.
