There is no reason for any sort of machine carrying trained humans to not give up its power to those humans in cases where the human brain is a better option over a computer.
I had no idea that this was the case. How does this work exactly? I can kind of see the reasoning behind not allowing human override of the controls. With a little imagination I am sure some of you can figure it out too. I mean I've only had about 15 seconds with the concept. The trouble is there aren't lots of situations where the human brain is a better option than a computer, but neither are we at the stage in cybernetics where a computer is any match for a human brain. So I ask again... how does the "computer" control the plane in flight? I understand computer landings and take-offs. I understand course maintenance via auto-pilot. Auto-pilots are hardly new and computer controlled landing and take-off is something I've heard about for at least a decade or more. You are alluding to something more that this in newer aircraft.

Besides MH370, what other recent crashes have no explanation?

An Airbus pilot just explained 3 post back that the computers can be overridden by the flight crew.

This plane did not crash at night.

Germanwings Flight 9525: "Everything is pulverized", said a policeman on the scene. What kind of event could do that? The entire plane blew up? It slammed into the mountain head-on? According to some of the photos, what's there is a hole filled with shrapnel-sized metal and remains...

Before I saw the images on TV I was hoping there would be survivors. Rescue team members said the plane basically disintegrated. Terrible news.

It really isn't time to even speculate but I've been in aviation quite a while and the only time I've seen stuff like this is when the aircraft hits nose first into terrain at full speed. The why's, how's and other stuff is useless to speculate on as there could have been any number of factors that we can't see from a few pictures the news is showing us.

Generally, mid-air explosions cause wider debris fields, and, believe it or not, there are generally larger pieces of debris than this. A fuel tank explosion, for example, may disintegrate the center section of the airplane but, generally, the tail and nose will tend to survive.

But, yeah, based on prior events like this, the plane probably hit nose first going extremely fast. Again, all the rest is useless to speculate on and isn't even worth the time. We'll have a pretty good indication of what happened very soon as the flight data recorder was recovered. The CVR won't be far behind.

Statement seems ominous. A commercial passenger plane hitting a mountainous terrain after a full speed, nose-down, "8-minute" descent from a cruising altitude of "38,000 feet"...

Don't be insulting. ( housewife )
My background?....
I'm watching the news like everybody else. I also did my own research.

So..
A pilot flying a Boeing for instance, can override the auto by pilots by forcefully break the controls.
Airbus however, is the way you described.

Airbus seems to limit their pilots more in extreme situations. For instance, the computer could stop a pilot from certain actions that normally would be less safe, however, it could be necessary in an emergency.

While the data available to us is minimal thus far, a debris field made up of mostly small fragments in a crater made from the impact from a plane in a steep decent (dive? we don't know how steep exactly) hitting the ground is consistent with many airline crashes of the past.

That's just what airframes do when traveling 400+ miles an hour and hit the earth at an oblique angle.
