On this day in 1945 General Douglass MacArthur moved his headquarters into Tokyo and began oversight of the rebuilding of a new Japan. Although his career would end in humiliation after the Korean war, MacArthur had a brilliant military career with the crowning achievement being the birth of Japan as an economic superpower. Because the country had largely been destroyed in the war, MacArthur used the US model to rebuild the government and the economy.
On this day in 1973 future president Jimmy Carter filed a government report on his UFO sighting 4 years prior. Described as "the darndest thing I've ever seen", Carter's UFO was a bright object with changing lights about the size of the moon, 30 degrees above the horizon. 10-12 other people witnessed the object and Carter vowed to release as much government information on UFO's as he could during his presidential campaign.
On this day in 1846 the struggling Donner Party sent two men ahead to California to bring back food after realizing they didn't have enough supplies to finish their journey. The 89 person wagon train had been mislead into believing that if they crossed the Sierra Nevada mountain range they would cut weeks off their trip. Instead they struggled to move across almost impassable terrain. One of the men sent ahead did return with the much needed supplies while the party was still in the mountains, but a snow storm trapped everyone for the remainder of the winter and things would go from bad to worse.
