We all know what it's like when there's a bug going around. More than a few people call in sick from work. Every time you cough someone says, "Oh, my sister just had that." When you go to the pharmacy, all of the medicines you need are sold out. In Milwaukee in 1993, it wasn't a bug that was making the rounds, it was a parasite, once which wrecked havoc to the intestinal tracts of those who caught it.

It was just supposed to be a fun night of dancing to a jazz orchestra just like every other Friday in West Plains, Missouri.

Not long after that, the building collapsed, trapping thousands inside the debris.

You don't expect a lake to just explode. But in 1986, Lake Nyos in Cameroon did exactly that on a hot August night, sending a jet of water skyward. The water wasn't the problem, however. The real problem was a mysterious something which killed over 1700 people and thousands of head of livestock.

On a hot summer night in 2015, a water park near Taipei hosted a party which drew thousands looking for a good time. But the party included an added ingredient which threatened the lives of hundreds of attendees.

On September 1, 2004, hundreds of students of all ages arrived with their families at School No. 1 in Beslan, North Ossetia-Alania, Russia for the start of the school year.

This year's Day of Knowledge festivities, however, wouldn't end in the first ringing of the school bell, but with gunshots.

Imagine what you could do when you were seventeen. Would you have been able to handle surviving a plane crash in the middle of nowhere? Or would you have been able to get up after the crash and start walking toward where help will hopefully be, even if it meant walking for ten straight days?
