Default Rouge Got Into Direct Law!

A321, nice work getting it on the ground uneventfully. Sounds like airplane induced, not operator induced.

Alternate law is very rare, and takes more than one thing going wrong... direct law is downhill from there. I don't know and have never heard of anyone personally who's been in direct law.

As you go from normal to alternate to direct, you lose protections along the way. In direct law you have none, you move the stick and the control surface moves proportionally. Since there's no mechanical feedback in bus FBW you have to be careful. You also have to trim manually with the wheel.

Law degradation can be caused by a variety of system failures, but it takes multiple failures to even get to alternate.

True to a certain extent, but other transport categories have their own protections as well, either artificial or just natural feedback.

In direct law you can stall or break the airplane with your wrist, without any warning or tactile feedback at all.

So for non airbus folk, anytime an airbus is in alternate law and you out the gear down it automatically goes into direct law. No further failures required.

One of the most challenging things I did in a simulator was flying the 747 classic with the feel turned off.

Flying in direct is not the same as what everyone else normally does, and all the Boeings, McDonnel Douglas, Lockheed, have featured artificial feel and feedback built into the flight controls to give the illusion that the pilot can feel the control. Turn that off, especially at high altitude, and it's quite easy to overcontrol the airplane.
