2007年12月12日,英国探险者戴维·亨普勒曼·亚当斯独自驾驶热气球挑战人类极限,创造了载人热气球飞行高度的世界纪录——9906米,打破了美国人卡罗尔·戴维斯保持了27年之久的9537米的纪录。这是年已半百的亚当斯第四次尝试挑战戴维斯的纪录。这一次,亚当斯驾驶18米高的热气球,12日从加拿大雷德迪尔保护区起飞,以每分钟152米速度上升,最终达到9906米高度,这一高度几乎超越了大型喷气式客机的巡航高度。
On December 12, 2007, British explorer David Heppleinman Adams piloted the balloon to challenge humankind alone and created a world record for the flight altitude of manned hot air balloons - 9906 meters, breaking the gap between the American Carol · Davis maintained a 27-year record of 9,537 meters. This is Adaes' 400-year-old fourth attempt to challenge Davis's record. This time, Adams drove a 18-meter hot air balloon and took off from the Red Deer Sanctuary in Canada on the 12th, rising at a speed of 152 meters per minute, eventually reaching a height of 9,906 meters, almost exceeding the cruise of a large jet airliner height.
