The entire flight lasts just 2.5 seconds and travels 41 feet — about the height of a four-story building — but Goddard quietly notes it in his diary as if describing a grocery run.
Robert Goddard's successful launch of the first liquid-fueled rocket laid the technical foundation for all modern spaceflight.
Because it is held in South America, all European teams must travel by ship — the voyage takes two weeks each way.
The 1930 FIFA World Cup was the first FIFA World Cup, the world championship for men's national football teams. It took place in Uruguay from 13 to 30 July 1930. FIFA, football's international governing body, selected Uruguay as the host nation, as the country would be celebrating the centenary of its first constitution and the Uruguay national football team had retained their football title at the 1928 Summer Olympics. All matches were played in the Uruguayan capital, Montevideo, the majority at the purpose built Estadio Centenario.

Chicago Pile-1 (CP-1) was the first artificial nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1 during an experiment led by Enrico Fermi. The secret development of the reactor was the first major technical achievement for the Manhattan Project, the Allied effort to create nuclear weapons during World War II. Developed by the Metallurgical Laboratory at the University of Chicago, CP-1 was built under the west viewing stands of the original Stagg Field. Although the project's civilian and military leaders had misgivings about the possibility of a disastrous runaway reaction, they trusted Fermi's safety calculations and decided they could carry out the experiment in a densely populated area. Fermi described the reactor as "a crude pile of black bricks and wooden timbers".

Ivy Mike was the codename given to the first full-scale test of a thermonuclear device, in which a significant fraction of the explosive yield comes from nuclear fusion. Ivy Mike was detonated on November 1, 1952, by the United States on the island of Elugelab in Enewetak Atoll, in the now independent island nation of the Marshall Islands, as part of Operation Ivy. It was the first full test of the Teller–Ulam design, a staged fusion device.
