Julian Nott (22 June 1944 – 26 March 2019) was a British balloonist who later lived in Santa Barbara, California. He was known for his record-setting achievements. Nott set 79 world ballooning records and 96 British aviation records. He developed balloons for flights to Solar System destinations, particularly Titan. He flew a working prototype Titan balloon at -175 C, approximately the temperature of Titan's atmosphere.

Life

Julian Richard Nott was born in Bristol, UK, on 22 June 1944 and attended Epsom College and St John's College, Oxford. He earned a master's in Physical Chemistry. After graduation Nott worked in Bangladesh with the Voluntary Service Overseas (VSO). In 1972, Nott piloted the first hot air balloon crossing of the Sahara. In 1973, he traversed the Alps in a helium gas balloon. Nott hypothesized that two millennia ago, the Nazca Lines geoglyphs could have been formed with guidance of Nazca leaders in a balloon, possibly the earliest balloon flights in human history. In 1975 to support this theory, he designed and piloted the Nazca Prehistoric Balloon, using only methods and materials available to the Pre-Inca Peruvians 1,000 years ago. Nott believed, “...setting a world record is indisputable proof of the success of a new design.” In 1979 he designed and built the first hot air balloon with a pressurized gondola. On a late October morning from Longmont, Colorado he flew this new balloon to world record 55,134 ft. It took Nott, in his balloon named "ICI Innovation," 1 hour 9 minutes and 42 seconds to reach the world record altitude. The ICI Innovation gondola is permanently displayed at the Steven F. Udvar-Hazy Center of the Smithsonian National Air and Space Museum at Dulles Airport. Nott pioneered the use of hybrid energy for lift, where solar power is a significant heat source, and using this technology in 1981 he crossed the English Channel. This hybrid balloon relied only the heat of the Sun to warm its lifting air during the crossing. For this historic flight, Nott used Dominic Michaelis’s solar balloon (aircraft registration number G-BAVU). On 22 August 1981, lifting off North West of Dover, he silently crossed the channel landing at Tournehem-sur-la-Hem of the Pas-de-Calais in France. Using the burner once, during the landing, to arrest the descent rate. The British Balloon Museum preserves the solar balloon G-BAVU envelope. On 1 November 1984, Nott became the first person to pilot a “pumpkin” superpressure balloon (SPB). He flew the SPB Wilson Endeavour across Australia from Pearce Air Force Base in Perth to Broken Hill. He believed this was his greatest achievement and planned to use the SPB to circumnavigate the globe. The superpressure balloon concept was further developed and used by NASA to carry unmanned payloads of up to 8000 lb at up to 110000 ft; circumnavigating the Earth for 7 to 55 days. Nott worked on the airships that flew over the 1984 Los Angeles and 2004 Athens Olympic Games. He developed a system for gas balloons in which conventional ballast is replaced with cryogenic helium. As Senior Balloon Consultant, Nott helped Alan Eustace break the world's highest parachute jump record from an altitude of 135890 ft on 24 October 2014. In 2017, Nott set a world record for the highest tandem skydiving jump, from 31916 ft. As an adjunct professor at Cal Tech and the University of California, Nott lectured on entrepreneurship for scientist, engineers, and mathematicians. His senior memberships include: American Institute of Aeronautics and Astronautics, Royal Institute of Navigation, Royal Geographical Society, and an Explorers Club Fellow. In March 2019, following the successful test flight of an experimental pressurized high-altitude balloon over Warner Springs, California, and after a successful landing, his gondola became loose and fell down a slope with Nott inside. At the hospital, he died from the serious injuries of this accident. Nott is buried at the Compton Village Cemetery in Compton, Guildford Borough, Surrey, England.
