Walton was an adventurous traveler. He also climbed Mount Kilimanjaro in 1989, sky dived at the North Pole in 2004, bungee jumped off the Bloukrans Bridge near Cape Town, South Africa in 2009, HALO jumped from 29,600 feet, and was a member of the first team of people to skydive over Mount Everest. Walton also continued to fly small planes, drawing on the training he gained in the Royal Air Force Volunteer Reserve. He was one of the first 100 people to pay for a trip into space through Virgin Galactic in 2004; after years of delays in getting the project off the ground, Walton was forced to ask for a refund in 2011, citing his advanced age.
