Bryson William Verdun Hayes completed a tandem skydive from 15,000 feet (4,500 meters) with members of his extended family on Sunday at an airfield in Honiton, southwestern England.
Among those jumping were Hayes' son, grandson, great- grandson and great-granddaughter.
At the age of 101 years, 38 days, Hayes broke the Guinness World Record held by Canada's Armand Gendreau, who jumped in 2013 at 101 years, three days.
When he landed, Hayes said he was "absolutely over the moon" at the achievement. The jump raised money for the Royal British Legion, a veterans' organization.
Hayes served in the British Army during World War II, and was awarded France's Legion of Honor for his heroic actions.
