The glass-bottomed balloon was designed to fly over the Alps and provide a view of the scenery below. It made its first flight at the 2010 Bristol International Balloon Fiesta.
Christian Brown created the world's only glass-bottomed balloon and claims that flying in it is a "terrifying experience." Brown is a veteran hot air balloon pilot with nearly two decades' experience. He even traveled around the world in a hot air balloon with Sir Richard Branson, but nether that experience or Brown's world record of 10,000 feet in a tethered hot air balloon prepared him for the fright of glass-bottom balloon flight.
