Birds nesting on sheer cliffs, the Arctic fox waiting below to devour the birds that fall short when they try to make the long glide off those cliffs to the safety of the water.

Today, fishermen along the country's coastline fashion simple fishing boats in a centuries old tradition while, a few miles away. motor vehicles glide off conveyor belts in state-of-the-art factories.

They can glide past eddies that would slow them down and then gain extra thrust by "pushing off" the eddies.
