Hindsight Bias is a wonderful thing
To all us arm chair critics. Hindsight Bias is great but when things go wrong in the aircraft sometimes speed and altitude are your best friend.
No aircraft or crew is infallible. Look what happened the the QANTAS A330 near Learmonth. No 1ADIRU played up and the auto voting/switching system failed. If the incident had happened at a lower altitude then the situation could have been much worse. Automation is good to a point but if it fails revert to s submode or take over and fly manually (if you have the time).
Rumour mongering helps no one.
