In the early years of manned space travel, Launch Complex 34 at Florida's Cape Canaveral played a key role in NASA's Apollo program – which of course led to that legendary “giant leap for mankind” when a human being first set foot on the Moon.
But not long before that history-making moment, a terrible tragedy took the lives of three astronauts on this very platform: Gus Grissom, Ed White, and Roger Chaffee were killed in a fire in their Apollo 1 capsule on January 27th, 1967. Though the site was decommissioned the following year, it remains standing today, with a plaque honoring the astronauts' bravery... and some people claim that their spirits continue to haunt the abandoned site, suggested by several reports of strange phenomena taking place there.
According to the travel blog Roadtrippers.com, locals claim to have heard screams near the launch pad, or felt “an overall dark feeling” when exploring the area. NASA has not addressed these reports, of course, but it's still a curious legend.
Bus tours of the site are scheduled often (though the government shutdown has those on hold for the time being), so maybe soon you can find out for yourself if those eerie tales are true...
