Glider

These are bi-plane like contraptions that fly in the air. They do not use an engine or Airbending to fly them; instead they are designed to glide on the air currents a lot like a kite. Like just about everything at the temple, they were designed by the mechanist. He came up with the idea when he saw pictures of Airbenders and found the old Airbender gliders lying around the temple. He modified these gliders and made it possible for non-Airbenders to use them.
