Apologize if I had you wrong on the notables.
Yes, that's the same link anon sent and same length as our footage. I need to pull it into an editor and analyze frame-by-frame to track nose elevation and acceleration/deccelaration.
It's possible the nose was coming down just at the beginning of the clip, but that is not a bounce. Controls were pulled up as it rolled out if so, but the plane should have stalled quickly unless nose pushed down.
