Amazing how quickly the NTSB can investigate an accident which kills someone important. The average time for a regular fatality is 18 - 24 months for a factual.
My thoughts exactly after waiting over two years for the report on an accident that claimed two lives, one of which was my fiance. The final report consisted of a single sentence...the same one that appeared in the NTSB Prelim issued over two years earlier! Of course, there was no investigation because there was "no one of importance" on board.
