Swiss Lunar Landing Hoax (1967)
An hour-long Swiss Radio broadcast announced that U.S. astronauts had just landed on the moon. The announcement generated enormous excitement. Telephone exchanges became jammed as people tried to phone friends to share the news. Even U.S. authorities in Switzerland initially weren't sure if the news was true or false.
The broadcast concluded with the report that the moonship would take off from the moon at 7 p.m. Listeners were urged to climb to a high vantage point, away from the city lights, to watch it return to Earth. As a result, there was a huge rush of people who tried to leave Zurich and get to the top of Mt. Uetliberg, overlooking the city. The railroad up the mountain had to add additional trains to handle the number of passengers.
