[serious] What is the worst scare you have had, thus far, in your life?

on a plane that had to land in a massive storm with a tornado within eyesight (far in distance, but still could see it).

Hail, luggage being thrown around, plane being blown around. Landed with emergency vehicles, with lights on, lining the side of the runway.

Immediately was boarded by police officers after a quick taxi to the gate, telling us to leave everything and get off the plane.

Updated my will the next day.
