To give the glider speed, Roland requested the Ministry of Construction to build a runway along the cliff towards the sea. It was designed with both ends curved upward like a crescent.
Once the glider was lifted and fixed in position, it could be released by unleashing the fixer. Due to gravity, it would glide forward and speed up until it darted out of the runway. The flyer would have a similar experience to sitting on a roller coaster in the modern world, though it would be far less thrilling.
Of course, these alone were insufficient as the wings needed more power to ascend. Thus, Wendy had to provide some wind to lift the wings.
Once the glider darted out of the cliff that was 15 meters above the water surface, it would have plenty of buffer space. Whether the glider ascended or descended, its slow speed provided both the flyer and rescuer time to prepare.
This was the reason why Roland designed the prototype to have two seats in the first place.
