To be a Pontifical Swiss Guard, one must be a Roman Catholic single Swiss man aged 19-30 who is beardless, attended Swiss military school and is at least 5 foot 8.
The Swiss guard was established on January 22, 1506 when 150 Swiss mercenaries pledged their loyalty to Pope Julius II. Now, they guard the Vatican, including the entrance to the Pope's private apartments. Source

On September 15, 1896, two locomotives were crashed head-on in a publicity stunt in Texas. The event became known as "The Crash at Crush." A similar stunt was successfully performed a few months previously.
For "The Crash at Crush," a special four-mile track was laid and two telegraph offices were built. For the crowd, two water wells were drilled, five tanks of water and several tons of ice were brought in and several hundred faucets were built. Three hundred policemen watched the 30,000 to 40,000 person crowd that sat 200 yards away in a grandstand.
The trains barreled closer and collided. "There was just a swift instance of silence, and then as if controlled by a single impulse both boilers exploded simultaneously and the air was filled with flying missiles of iron and steel varying in size from a postage stamp to half of a driving wheel."
Three were killed and six were seriously injured. Souvenir hunters cleared debris, the railroad made quick compensation and a ragtime song was composed to memorialize the event.
