The interesting part seems to be happening around 1:20-1:30 minutes into the video. The main wings and canadards (that's the smaller wings at the front) are oriented fully parallel to the direction of flight. The threads indicating the flow of air over the surfaces are no longer moving around and therefore air is moving smoothly over the wings. The aircraft seems to be relying fully on lift provided by the wings instead of the engines. As far as I know they hadn’t achieved that before. The thrust required for level flight with lift provided by wings is said to be ~ 10% of what is required for vertical take-off and landing. https://youtu.be/ywJWka1evH8?t=82 https://youtu.be/ywJWka1evH8?t=82
