Oh my goodness, someone's mom flying the airplane! That's so dangerous.
The reality is she is flying at high alititude and cruise mach. That's harder than hand flying at 16,000'.
Video also shows the pitch sensitivity(look at VSI/VVI in the video), and small control movements, required at high altitude. Might be a good video to show non jet guys transitioning to jets.
Hand flying the 787 by a non-rated guy on a non-commercial flight, especially at medium altitudes? Non event.
