This is a brilliant reconstruction of the Jan 2 crash at Haneda-Tokyo airport: https://asia.nikkei.com/static/vdata/infographics/haneda-runway-collision/
My flight departed Haneda only 2 hours before this crash. I learned of the crash at my destination, so quickly called my family o reassure them that my flight was not involved. Phew!
As in almost all aviation crashes, this crash was the result of a series of errors.
