Don't think there's much more to learn from armchair expert observations of the #Haneda collision, but I've always found the reports fascinating.
They show how diligent and thorough the investigations are, as well as everyone and every aspect of the systems involved in #aviation.
The analysis of the aircraft equipment, crew resource management, passenger behaviour, airport layout, inspections and procedures all contribute to understanding where the "Swiss cheese" holes lined up. Anyone interested in #Safety and especially #Space should take a read through such reports.
