US figure skater Nathan Chen became the first person to land six quadruple jumps at the Winter Olympics during the men's free skate event. The performance came after Chen faltered in his earlier Olympic appearances. On Twitter, former US Olympic figure skaters like Michelle Kwan and Scott Hamilton gushed over Chen's jumps and historic performance. Figure skater Nathan Chen got off to a rocky start at the 2018 Winter Olympics in Pyeongchang, falling a handful of times during the team event and the men's short program. But during the men's free skate, which aired Friday night in the US, he redeemed himself in a huge way: Chen became the first Olympian to land 6 quadruple jumps, or quads, in a single performance.
