1907: Mexican railway worker Jesús García performs an extraordinary act of bravery when he drives a burning locomotive loaded with dynamite away from the town of Nacozari, in the Mexican state of Sonora. The train was carrying explosives for the local copper mines when a fire broke out in one of the wagons. Realising that the dynamite could explode and devastate the densely populated town, he ordered his fellow workers to get off the train and took control of the locomotive himself. He made it six kilometres before the explosives detonated. Some did die, including García himself, but many more lives were saved.

2000: No winner can be declared in the United States presidential election, prompting a controversial recount in Florida. A month later the Supreme Court rules that the recount should be halted and the original results be certified, thus making George W. Bush the next US President.

2006: Multiple witnesses, including pilots, mechanics and ground staff, report a dark, saucer-shaped object hovering over a United Airlines gate at Chicago's O'Hare International Airport. The object is said to have shot upwards through the cloud layer, leaving a circular opening in the clouds that subsequently closed. The incident attracts significant media attention.
