Feeling hot this summer? It could be worse. In January of 1719 during the Great Northern War, six thousand troops from the Swedish army began what should have been a two-day walk back over the Norwegian border to their own empire, mentally and physically exhausted from a four-month-long losing battle. But then the snow came, and what was supposed to be a two-day hike turned into a week-long nightmare.  

One country said it was a tragic mistake during wartime. One country claimed it was a deliberate and heartless act. But one thing was true - whether it was one or the other, the shootdown of Iran Air Flight 655 took the lives of 290 innocent people in July of 1988.

It's time for the yearly school trip - no, not to Washington, DC, or the Grand Canyon or New Orleans. In 1986, as every year before it, the kids in the Basecamp program at Oregon Episcopal School participated in a special trip - a climb up Mount Hood in the Cascade mountain range. But when the group left the school late on the night of May 11th, 1986, to head to Mount Hood for the opportunity of a lifetime, they had no idea nine of them would not be coming back alive.

It's 1942, and it's men in uniform and women in pretty dresses everywhere you go. Tonight's you're at the Cocoanut Grove, arguably the most popular supper club in Boston. The decor matches the name, with a tropical theme and fake palm trees surrounding a dance floor bracketed by Spanish-tiled eaves. You and your steady beau are all set up with drinks and ready to watch the floor show when there's a commotion from the direction of the stairs down to the basement Melody Lounge. Is it the fight it sounds like? Or is it something far, far more dangerous?

In two weeks, it will have been three years since a man walked into Pulse in Orlando, FL, bearing a rifle and intent on turning the last day of that city's Pride week into the last night many in the popular gay nightclub would ever see.

It was something you wouldn't wish on your worst enemy. On June 5, 2009, a spark caught on the other side of the wall of the ABC daycare center in Hermosillo, Mexico. On that side of the wall, a growing fire. On the other side, over a hundred and forty children between the ages of six months and five years old and only six adults to watch them - and save them when the fire broke through.

There's only a half an hour before the end of the school day, and your teacher is working through her final lesson - geography, geometry, Shakespeare. Then you think you smell something - a whiff of smoke. The room starts to warm up. In only a few short minutes, you and the rest of your classmates find yourself with a horrific choice - burn to death, or leap down to the pavement below? The young students of Our Lady of the Angels Catholic elementary school in Chicago, IL, faced that very decision on the first day of December in 1958.

All it would take was one spark. The southeastern Australian state of Victoria was dried out and temperatures were tipping into the high forties Celsius. In early February of 2009, the region could burn so very easily. Everyone knew February 7th was likely to be the day that summer Victoria burned. 

There are certain things you don't want to see out the window when you're sitting on a plane that's taking off. Seeing pieces of the plane fall off - like, say, the engine - are pretty high up on the list. Passengers sitting on American Airlines Flight 191 as it took off from O'Hare International Airport on May 25, 1979, were horrified to look out their windows and see exactly that happen to the engine on the left wing. They would only be horrifed for another thirty-one seconds.

What do you do when your home is no longer safe enough to be a home anymore? You try to find a new home, even it means hurrying things along for your own protection. The Jewish refugees on board the MS St Louis in May of 1939 were looking for just such a place. All they found were doors slammed in their faces.
