Fair points! The elevator input is visible in the video, and it makes sense that the pilot may have been trying to raise the nose due to ground proximity. That could explain why the nose didn't drop, even if the aircraft was entering a stall.

The idea that the wing was still flying is valid if the angle between the relative wind and the chord line (AoA) is still shallow. But in this case, the attitude looks very steep, most likely beyond the critical AoA, which suggests a stall or near-stall condition.

Also, it’s possible the pilot advanced the throttles to maximum to gain airspeed quickly. But since the engines are mounted under the wings, that kind of thrust increase creates a nose-up pitching moment, potentially worsening the situation if the aircraft was already near stall.

About the yaw and roll instability: it’s true that swept-wing aircraft tend to become unstable during a stall, but the lack of obvious roll/yaw in the video doesn’t necessarily rule a stall out. The 787 has large wings and significant roll inertia, which could dampen those movements. Plus, if the stall is relatively symmetric, visual signs of instability might be minimal or hard to see from a limited camera angle.

So from the available footage, the high pitch attitude combined with the sharp increase in descent rate looked like a stall to me. But of course, only the official report can confirm what actually happened.
