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

best way to go 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.


Good grief.



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

Yes, I'm sure that's what you call a touch and go.

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


Of course you would.
