Every adrenaline junkie would enjoy a flight in the world’s first glass-bottomed balloon. It made its first flight at the 2010 Bristol International Balloon Fiesta. The balloon with transparent floor was created by Christian Brown, who has been hot air pilot for 18 years, traveled around the world in a balloon with Sir Richard Branson and holds the tethered altitude world record at 10,000 feet (3,050 m).
