WebOverview. Wave Gliders are long-duration ocean robots that help scientists, businesses, and governments gain new insights and improve decision making. Operating at the surface, these autonomous surface vehicles provide the essential link between sea, air, and space. They expand how we collect metocean and marine data, bridging a data and access ... WebHang glider just after launch from Salève, France. Hang gliding is an air sport or recreational activity in which a pilot flies a light, non-motorised foot-launched heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or composite frame covered with synthetic sailcloth [1] to form a wing.
