Nerval's Lobster writes: Twenty-six photos of the space shuttle Challenger disaster have appeared online. According to io9, "Michael Hindes of West Springfield, MA, was sorting through boxes of his grandparents' old photographs when he happened upon 26 harrowing photos of the Space Shuttle Challenger Disaster of 1986. To his knowledge, these photos have never been publicly released." Hindes told the Website that the photographer was "a friend of his grandfather, who worked for NASA as an electrician on the Agency's hulking, spacecraft-schlepping crawler transporters." Someone at Reddit (which also has a lengthy thread devoted to the images) also threw together a GIF of the liftoff and subsequent explosion.
