In 1958, the nuclear-powered submarine USS Nautilus became the first vessel to cross the North Pole underwater.

In 1981, U.S. air traffic controllers went on strike, despite a warning from President Ronald Reagan they would be fired, which they were.

Ten years ago: Toyota said its April-June 2007 profit had jumped 32.3 percent to a then-record high for a quarter, lifted by strong overseas sales and a weaker yen. Iraqis welcomed home their soccer team, which had won the Asian Cup.

Five years ago: The U.N. General Assembly overwhelmingly denounced Syria’s crackdown on dissent in a symbolic effort meant to push the deadlocked Security Council and the world at large into action on stopping the country’s civil war. Michael Phelps rallied to win the 100-meter butterfly for his third gold of the London Games and No. 17 of his career. Missy Franklin set a world record in the 200 backstroke for the 17-year-old’s third gold in London. Falling at speeds of up to 220 mph, 138 skydivers shattered the vertical skydiving world record as they flew heads-down in a massive snowflake formation in northern Illinois. (This record was in turn eclipsed in 2015 by 164 skydivers plunging over central Illinois.)

One year ago: President Barack Obama cut short the sentences of 214 federal inmates, including 67 life sentences, in what the White House called the largest batch of commutations on a single day in more than a century.
