It was a "freak" accident because so many holes in the cheese had to line up that day;
"Freak accident" and its sister cliche of convenience "isolated
incident" are only heard in politics where the involvement of
politicians was the sole cause of the event (ie they cannot pin
it on anyone else), not in real life. And definitely not in aviation
Almost all aviation prangs are full of lined-up cheese holes eg
SQ006 under the same false rationale could also be classed a
"freak accident", as could Lima, Helios, etc.
