Hmmm... you have never seen the video of the Airbus A320 flying through
the trees prior to crashing at the Paris Airshow several years ago, have

That was an anomoly. But, in any case, that was a auto-flight/flight controls
design and operations issue. My previous comment, as you can see, was about
flight instrument displays and navigation systems.

It might have been an anomoly, but it was not surprising given the history
of introducing new technology and the resulting discovery of new failure
modes.
