Can you imagine in your whole life to make a journey which is like a bird? You think it’s impossible but it’s not impossible because you can fly in air through hot air balloons and enjoy your flight.Hot Air balloon which also called balloon aircraft, airships and thermal airships.On Nov 21, 1783, in Paris, France, the first untethered  manned flight was made by Jean-François Pilâtre de Rozier and François Laurent d’Arlandes in a hot air balloon created on Dec 14, 1782 by the Montgolfier brothers.Beginning in the mid-1970s, balloon envelopes have been made in all kinds of shapes, such as hot dogs, rocket ships, and the shapes of commercial products, though the traditional shape remains popular for most non-commercial, and many commercial, applications.The term hot air balloon is occasionally used inaccurately to denote any balloon large enough to carry people, including gas balloons.Today, hot air balloons are used primarily for recreation.You can see some weird and eye-catching hot air balloons below.
