OK, it’s semantics.
arrival 1: the act of arriving 2: the attainment of an end or state
I say a cataclysmic crash is in no sense an arrival, except perhaps ironically.
Certainly, the 1st sub-definition describes my intended point.
Politically, I suppose the flight was a disaster, but from the engineering standpoint, the team made progress.
Checking out, g’night.
