There is a line in the main article that said whenever the crew would take proper corrective action the alarm bells would sound telling them they were wrong. In short, there was a tremendous instrument failure with mis-direction. The crew apparently could not overcome “the double whammy.”
Which is why the basic flight instruments should never, ever be capable of being overridden by computer and they should always be part of emergency procedures and flight recovery procedures.
If a crew suspects flight computer errors that endanger an aircraft I evangelize that that there must always be instruments that can be trusted. Instead, we get these "cool" electronic displays that are fed by software. I only fly small airplanes but even they have analog instruments that I can trust when the flat panels fail, and they do fail.
Here is one instrument panel of a plane I fly and notice it has the analog instruments at the top. Nice and sweet. When those G1000 displays go blank or the flight computers get confused those round dials work just fine. It is a rude awakening to be flying at night near the mountains and have those panels go blank and reset.
