Click to take off. Click again to pull up. This increases altitude (duh), but depletes the battery. After pulling up, the plane will naturally descend. This trades off altitude for an increase in speed. Click once more to level off. Repeat steps 2 and 3 until the plane inevitably land in the ocean. You'll be ranked based on your traveled distance, top speed, and flight time.
