"The hot air balloon is the oldest form of flight technology used for carrying humans, following the first manned flight in 1783. The balloon itself consists of an envelope, which is used to contain the hot air, and a gondola, where passengers and a means of creating hot air are typically housed. The heated air inside the envelope has a lower density than that of the cold air outside, and this causes the balloon to rise. Hot Air Balloon Day is an annual celebration that marks the impact hot air balloons have had on travel and leisure.
Although out of the reach of many, the most common means of celebrating Hot Air Balloon Day is to take a hot air balloon ride. Although not ideal for those that are afraid of heights, or flying, there are companies and hot air balloon owners that offer special deals for these celebratory flights."
