Alicia Hempleman-Adams, a 36-year-old British adventurer from Bath, has made history by becoming the first woman to cross the Atlantic Ocean in a hydrogen gas balloon. Her journey aboard the Atlantic Explorer began on June 4, launching from Presque Isle, Maine, and concluded on June 7 in Bastendorf, Luxembourg. Over four days, the team of three, including pilots Bert Padelt and Peter Cuneo, traveled 5,282 kilometers at an average altitude of 14,000 feet, requiring supplemental oxygen to combat hypoxia. The crossing was particularly notable as it utilized hydrogen instead of helium, a first for transatlantic balloon flights. Hempleman-Adams expressed pride in their achievement, recounting the difficult conditions they faced, including ice accumulation on the balloon. She is the daughter of Sir David Hempleman-Adams, who previously made a solo crossing in an open basket balloon. This remarkable feat marks a significant milestone in ballooning history, as the team is only the second to attempt a hydrogen-powered transatlantic crossing, following a failed attempt in 1958.
