Ruppert Composite Specializes in Gliders that don’t have engines. This one being the Archaeopteryx A fully functional glider with a hole in the bottom to stick your feet out and actually run during takeoff. You can only imagine running, and then jumping while trying to stick your feet in the craft all while trying to fly and glide a huge machine. If these were cheaper, then we would see some serious injuries. The Glider Launch is a fun thing to watch, but completely different when you have to be inside and doing it yourself.
