Hot air balloon – an aircraft lighter than air, whose operating principle is based on Archimedes’ principle. To create a lift is used in the shell enclosed gas (often simply heated air) with a density less than the density of the surrounding air.
If the balloon to attach the engine, it will be an airship.
Hot Air Balloons for the first time allow a person to get off the ground, and later reach the stratosphere. Hot Air Balloons, rising to a height of more than 11 km is called the stratosphere Hot Air Balloon.
During the Second World War, Hot Air Balloons were used extensively to protect cities, industrial areas, naval bases and other facilities against attack from the air. Action barrage Hot Air Balloons was calculated damage to aircraft collision with ropes or shells are suspended on ropes explosive charges.
During the Cold War, automatic drifting Hot Air Balloons (ADA) has been widely used in Western countries to conduct reconnaissance over the territory of the USSR. Machines were unobtrusive, self-contained, relatively cheap, and fly long hard while altitudes above 20 kilometers. This made it difficult ADA detection and destruction inadequately expensive.

Current altitude record set October 24, 2014 Alan Yustas, rising to a height of about 41,421 meters in the suit, attached to the Hot Air Balloon over the US state of New Mexico.
altitude record for a manned Hot Air Balloon bench was installed May 4, 1961: starting from the deck of the ship USS Antietam in the Gulf of Mexico, the Hot Air Balloon rose to a height of 34.7 km.
40,814 kilometers of flight in 19 days 21 hours and 55 minutes (average speed – – 85.4 km / h) March 1, 1999 the first non-stop round the world flight was made in a Hot Air Balloon.
altitude record for unmanned Hot Air Balloon is 53.0 km. The Hot Air Balloon was launched May 25, 2002 in Iwate Prefecture, Japan. This is the greatest height ever reached aeronautical apparatus. Only rockets, rocket planes and artillery shells can fly higher.
Well, we are on the Hot Air Balloon Festival in Italy.
“This is a great way to see the world. It’s not like what you see from an airplane or helicopter. Here is an overview of 360 degrees, and do not know where the arrivals where you land. This is a truly extraordinary “
