RE: Flying wing gliding in high winds
The balloon and glider are both travelling with the wind, the glider will simply orbit the balloon if it is trimmed to fly in a circle. Neither have any idea that the wind is moving them over the earth. You, on the ground, will see them both moving away downwind. If you don't want to chase the glider too far, then you will have to trim it to fly dead straight, and release it straight into the wind. The glider will always fly at trimmed speed, its speed over the ground will be the vector sum of the wind and glider speeds.
