Hand flying imc
My first two flag carriers did and probably still do hand flying on a nice day.
My last did It when the weather was cr*p especially sensible because of intrusion of unmonitored general Aviation in our airspace on nice days.
When things go wrong it’s often on those dirty days when you are tired...anyone can fly and trouble shoot on a sunny morning.
After the frogs got it wrong there was a similar incident out east..the crew said they only just managed and if it hadn’t been in relatively good weather at the start of their day it would have probably turned into another accident.
