I hope this is not the foundation for this accident!
25000-30000 hrs, the majority long haul boredom, then retirement and into the world of short haul on an unfamiliar aircraft, and with new SOP.
What was his age when he crashed? As BOAC said; "With my eyesight; I could probably not see an airport from 10 miles".
Age does not improve ones vision, and after 60, things start to go downhill quite fast.
With (allegedly) two aircraft diverting before this accident, one have to ask why this captain saw the situation differently.
