The first modern hot air balloon was designed and built in 1960 by Ed Yost. He made the first free flight of such an aircraft in Bruning, Nebraska on 22 October 1960. Initially equipped with a plastic envelope and kerosene fuel, Yost's designs rapidly moved onto using a modified propane powered "weed burner" to heat the air and lightweight nylon fabric for the envelope material.
Today, hot air balloons are used primarily for recreation. There are some 7,500 hot air balloons operating in the United States. Since piloting a balloon requires some effort (licensing and purchase of equipment), many people opt to purchase a balloon flight from a company offering balloon rides. Balloon rides are available in many locations around the world and are especially popular in tourist areas.[5] Balloon festivals are a great way to see hot air balloons close up, and are an enjoyable family outing. Balloon festivals usually include other activities like live entertainment, amusement rides, etc.[6]
Hot air balloons in flight
Hot air balloons are able to fly to extremely high altitudes. On November 26 2005, Vijaypat Singhania set the world altitude record for highest hot air balloon flight, reaching 21,290 meters (69,852 feet). He took off from downtown Bombay, India and landed 240 km (150 miles) south in Panchale. The previous record of 19,811 meters (64,980 ft) had been set by Per Lindstrand on June 6, 1988 in Plano, Texas. However, like all registered aircraft, oxygen is needed for all crew and passengers for any flight that reaches and exceeds an altitude of 12,500 feet.
On January 15, 1991, a balloon carrying Per Lindstrand (born in Sweden, but resident in the UK), and Richard Branson of the UK flew from Japan to Northern Canada, completing 7,671.91 km. This record was shattered on March 21 1999 when the Breitling Orbiter 3 touched down in Egypt, having circumnavigated the globe and set records for duration (19 days, 21 hours and 55 minutes) and distance (46,759 km).
With a volume of 74,000 m (2,600,000 ft), the balloon envelope was the largest ever built for a hot air craft. Designed to fly in the trans-oceanic jetstreams the Pacific Flyer recorded the highest ground speed for a manned balloon at 245 mph (394 km/h).The first modern hot air balloon was designed and built in 1960 by Ed Yost.
