Worst aviation disaster in history. Basically the pilot initiated the take off during poor visibility and without proper take off clearance despite his cabin crew repeatedly voicing doubts about the runway being clear. The plane taking off crashed into another plane that hasn’t cleared the runway yet, killing 583 people.

This accident lead to several changes in aviation procedures, including Crew resource management. The captain overruled legitimate concerns of his crew by pulling rank - now the procedures call for every cabin crew member having equal voice in concern to flight procedures. Also :

The word “takeoff” is now spoken only when the actual takeoff clearance is given, or when cancelling that same clearance (i.e., “cleared for takeoff” or “cancel takeoff clearance"). Until that point, aircrew and controllers should use the word “departure” in its place (e.g., “ready for departure").

That was also a point of confusion due to garbled radio calls.
