Russia's Zvezda television channel has released new footage of Su-57s engaging in maneuvers, this time showing a caravan of four Su-57s flying at an Astrakhan test range.
In the video, pilots can be heard chattering as their planes glide in close formation. An alarm (possibly indicating proximity) is heard. Later, footage shows a Su-57 performing a dizzying free-fall maneuver with its engines shut off while rotating horizontally before stabilizing and continuing its descent.
