For the very last time, I was pointing out that the kick it straight

whether it's done by a human, computer or chimp.

That's the part I disagree with. This was not a good demo of the kick
it straigh technique. It was a great demo of how to do it wrong.
That's because the computer doesn't know how, and won't let the human
do it. AFAIK, the chimp is probably still at the board meeting.
Watching that video tells you absolutely nothing about the relative
advantages and disadvantages of the kick it straight technique. It
demonstrates nothing other than the peculiarities of some poor
software.

That software may have saved the plane, because
it knows the limitations of gyroscopic coupling that
the engines will force into the airframe and then
into the A/C attitude.

A *gentle* "kick it straight" from crabbing has limitations
of the rate of angular change, because you're torquing
large spinning turbofans, which act like gyros.

That sudden x-wind gust, took the landing way beyond
safe, or even possible. An ultra fast rotation applied by
the pilot may have throwen an engine, disengaged
blades, warped the airframe, overstressed bearings,
all of the above and more.

All and all, it was probably the best outcome to recover
from that anomalous gust....touch and go.

PS: I'd pay extra to have been on that plane!
