"Got a notification from my smart home app in the middle of the night saying 'Your doorbell detected a visitor.' Yes, this was real. Basically, I kept getting notifications on my app that my doorbell detected a visitor, yet when i checked the first few times nothing appeared, and figured it was maybe a stray dog or someone on the sidewalk being detected by the sensor. Several notifications later I checked again and this is what appeared. Yes I am alive" -FatNDepressed

Been through most of the thread and didn’t see this one yet. In 1975 two brothers, Michael(18) and Sean(12) Mcquilken of San Diego ascended up Moro Rock in Sequoia National Park. It was a stormy day and their sister Mary(15) took this photo as they were amused. It began to hail, and as they were descending Sean was struck by lightning. -surzirra

The Elephant's Foot: it's the melted reactor core in Chernobyl. The amount of radiation from it was fatal within a minute and even a short exposure would leave you sick and dizzy for weeks afterward. At the time the picture was taken it would be "safer" to approach but still fatal within 500 seconds. -ONI_Section_3 The graininess of the photo is in fact not age, but trace amounts of radiation affecting its quality.

The remains of the astronaut Vladimir Komarov, a man who fell from space, 1967. -coxeta Komarov knew the space capsule wasn’t flight-ready, but also knew that if he declined to fly, his backup and best friend Yuri Gagarin would have to make the fatal trip instead. Komarov decided to sacrifice himself, and refused to let Gagarin board the vessel during takeoff. As the capsule inevitably malfunctioned and fell from orbit, with Komarov headed to his doom, US listening posts in Turkey heard him crying in rage and "cursing the people who had put him inside a botched spaceship."

These photos are stark reminders of the horrors of war.

These photos are a mysterious documentation of the last days of two lost hikers.

via: Imgur

Basically, two girls disappear during a hike in Panama. 10 weeks later, their remains are found, just bone fragments and a few of their equipment is left. There is a camera that has images. It starts off with normal images of the girls playing around as you would on a hike. You can see in the images they get lost at some point. The images abruptly stop after that. About 10 days later, 90 images are taken, most are dark, but a few show rocks and branches. One shows a bloodied hair of one of the girls. The fate of the girls during and after those ten days leading to their deaths remains a mystery. All we know is that they attempted a few times to call the police, but no reception. The last being ten days after the disappearance. . -aj240

The Odessa Catacombs

A network of tunnels underneath Odessa, Ukraine make up the Odessa Catacombs—which are even larger than the catacombs of Paris. Most frighteningly about these catacombs are the number of people who have died there, either by murder or by simply getting lost and never emerging. A young woman, Masha, took a wrong turn and became lost, perishing in the catacombs in 2005, and her body was not retrieved for two years after that.

And speaking of the Paris Catacombs...
