A discus launch glider is a special kind of airplane that you can throw like a frisbee. It's called a glider because it doesn't have a motor to fly on its own, but it can glide through the air and stay up for a long time.
When you want to fly a discus launch glider, you first have to hold it by the wing and spin around in a circle. This is called winding up the glider. When you release the glider at just the right moment, it will shoot up into the air like a rocket!
The glider is designed to be very light and aerodynamic, which means it's easy to throw and can fly really far. And since it doesn't need a motor, you can launch it again and again without running out of power.
Some people really like flying discus launch gliders because it's a fun challenge to see how high and far you can make it go. Plus, it's a great way to get outside and enjoy some fresh air and exercise!
