There is no way either of these graphs is possible when the plane went into a stall condition almost instantly with the center of gravity 12 feet behind the center of lift. Planes cannot fly unless they are balanced. The plane was unbalanced. . .

Planes sure can fly unbalanced, especially if they have momentum. If the condition is extreme they will stop flying at some point, as TWA800 did.
Here’s another example:

Your point on that video? That cargo plane was on take off, hence the extreme climb, then lost its engines, and could not continue its take off acceleration. No air speed, no lift, while it was trying to take, no resistance to drag, and no climb. It only appeared to climb a short distance (and there may have been some because there was still a bit of lift and the momentum) after the loss of engines because of the camera angle. It was still balanced until stall eliminated all lift. It still had its nose and unless it’s cargo all shifted backwards toward the tail, it was balanced. That plane had other problems which caused the engines to stop producing thrust and caused it go into an obvious stall and stop it from flying. There was sound on that video and there was no engine noise. Ergo, no engines were operational working when it appeared on the video.
