First up, there’s a Norse legend that has 12 gods sitting down to a banquet when the uninvited Loki shows up, making it a party of 13. He killed one of the gods, resulting in Ragnarok— the death of several gods, natural disasters, basically the biggest catastrophe on earth that left only two human survivors.
Apollo 13 is the only unsuccessful moon mission so far. An oxygen tank exploded and the survival of the astronauts was really up in the air (no pun intended) for days until they all came home safely.
The Thirteen Club was a group in the late 1800s that really wanted to debunk the legend that 13 people at a table would always result in the death of one of them the next year. They would meet on the 13th of the month and have a 13-person dinner. To make things even more interesting they would spill salt on the table— and NOT throw it over their shoulders (shocking).
They fined members 13 cents for showing up late. 5 presidents were members of this strange club: Benjamin Harrison, Grover Cleveland, William McKinley, Theodore Roosevelt and Chester A. Arthur.
