• 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]

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]
