21. For a time soon after World War II Yugoslavia was a leader in gliding flight and glider design. 22. On the other hand, modern ram-air parachutes are essentially inflatable wings that operate in a gliding flight mode. 23. They are unique among lacertids in being capable of gliding flight between trees up to 30 m distance. 24. The kinetic energy that develops during the dive flight is utilized in the second phase of glide flight . 25. This gliding flight is regulated by changing the curvature of the membrane or moving the legs and tail. 26. To achieve gliding flight , it uses two membranes ( patagia ) which fold up when not in use. 27. Nothing like this structural mechanism for gliding flight has previously been found in any creature living or extinct. 28. The Giant Hummingbird is distinct from other Hummingbirds in flight with occasional gliding flight observed, very rare in Trochilids. 29. It contains the only known British example of a gliding reptile, the oldest known vertebrate capable of gliding flight . 30. The eagle patrols the boundary of this home range and advertises its ownership with high-altitude soaring and gliding flights .
