1986
1986 was a year of tragedy, with the explosion of the U.S. space shuttle Challenger, killing all seven crew members, and the explosion of the Chernobyl nuclear reactor, killing two instantly and many thousands over time. But it also had brighter moments: Hands Across America united 5 million people from coast to coast, Oprah Winfrey debuted her iconic talk show, Halley’s Comet made a triumphant return after 76 years and the Voyager completed the first around-the-world flight without refueling.
