Abstract: An aerodynamic flying toy ball apparatus comprised of a plurality of semi-rigid uniformly shaped semicircular fins joined along, and angularly arranged radially around a longitudinal axis, balanced for aerodynamic gliding flight with slight up elevator to create a stable 3-D ball shaped glider capable of gliding and maneuvering (climbing, turning and looping) as a gliding airplane. The apparatus resembles a ball and can roll on the ground. The apparatus can be made from a variety of lightweight materials. Optional features include a small extra fin for holding and throwing the apparatus, provision for catapult launch, and semi-elliptical fins and/or holes in fins to optimize flight and rolling performance.

Abstract: A fixed-wing flying apparatus, aircraft, airplane or device is provided which is capable of stably gliding in more than one direction such as backwards, frontward or sideways. The device comprises a plurality of wings arranged around the center of area and defining a space therebetween. Each wing includes an outwardly protruding wall along an outer edge of the wing, which disrupts airflow over the wing flying in front so it is less effective than the wing flying behind, facilitating temporary or long term sustainable speed-seeking glide stability in more than one forward direction without any trim or center of gravity adjustment. The plurality of wings can include two wings, three wings forming a triangle, or four wings forming a square or rectangle. The aircraft can be unpowered, powered, free-flight or controlled. A one-front airplane can also be constructed with very relaxed yaw stability.
