Someone on reddit pointed out this happened exactly 804 days after Malaysia Airlines 370 vanished. Weird coincidence.
Oh wait. Flight number is 804: 8 + 0 + 4 = 12
66 people aboard: 6 + 6 = 12
Must mean something!
str('66') + str('6') = '666'
it's the devil.
Don't underestimate the difficulty of a SAR operation, especially at sea.
