Baker, a law student at the University of Minnesota, had determined that since state law did not prohibit a marriage between people of the same gender, he and his partner would have the same rights as a man and a woman. The deputy clerk, Robert Anderson, had the gentlemen swear that the information on the license application was true, and advised that his office would consult Hennepin County attorney for advice whether the license to wed could be issued.^[109] Hennepin County Attorney George M. Scott recommended on May 22 that the license be denied and, referring to a law requiring a marriage license to be issued in the county in which the woman resides, and a 1949 case noting that it was the duty of the state to guard marriage "in the conservation of public morals". To permit two males to marry, Scott concluded, would "result in an undermining and destruction of the entire legal concept of our family structure in all areas of law."^[110] District court clerk Gerald R. Nelson stated that he would abide by Scott's recommendation and deny the license^[111] In 1971, McConnell and Baker were granted a license in Blue Earth County, Minnesota and a marriage ceremony was performed; though challenged, it was never invalidated.^[112]

• Based on a computer simulation in 2010 of the flight data from Apollo 13, an analyst has determined that if the ill-fated mission had failed to return to Earth following the April 13 explosion of one of its oxygen tanks, the spacecraft would have returned to Earth orbit after drifting for five weeks, traveling 350,000 miles (560,000 km) away from the Earth before its path brought it close enough to the Moon's gravitational field to propel it back toward Earth. According to the simulation by Analytical Graphics, Apollo 13 would have re-entered the Earth's atmosphere on May 20 and would have been incinerated. Previous predictions had been that the Apollo 13 astronauts would have missed the Earth by 40,000 miles (64,000 km) and drifted in space indefinitely.^[122]

• The 120-year old Britannia Bridge, an historic landmark that connected the Welsh island of Anglesey to the British mainland, was heavily damaged and rendered impassable by when two teenagers accidentally set it afire.^[127][128] The tubular bridge across the Menai Strait had been built by structural engineer Robert Stephenson and had carried rail traffic since 1850. Although the island's 57,000 residents could still drive across the strait on the Menai Suspension Bridge, the primary source of Anglesey's economy—the use of the port of Holyhead to transport cargoes between the United Kingdom and Ireland—was shut down by the loss of the railroad.^[129] A reconstructed bridge would finally open to rail traffic on January 30, 1972, after British Rail's spending of £3,250,000,^[130] equivalent to GBP £49,858,000 or US$61,000,000 in 2019.^[131]

The borehole itself is only 9 inches (230 mm) in diameter. At that depth, however, the temperature was 356 °F (180 °C), far higher than predicted, and the drilling columns had broken, making further drilling impractical.^[133]
