The wing vortices descend as they move out from the point of generation. The drone is level with the top of the aircraft as it passes, and so it remains above them.Ok, so we're saying it's real, no helicopter with a long range lens, and the drone used a wide angle lens. Then please explain with the drone being so close how it managed to stay stable while encountering the tremendous wake turbulence created by the AN-225.
Here's the wake turbulence from an A380, similar in size to the AN-225 (30 more feet of wingspan for the AN-225).
