As early the 200s AD, Kongming lanterns, (which essentially were miniature lantern/hot air balloons) were used in China for military signaling. However, the first manned hot air balloon flight (which was tethered to the ground), was done by Joseph-Michel and Jacques-Etienne Montgolfier in Annonay, France on October 19, 1783. The first untethered hot air balloon flight was done by the same brothers, in the same town, on November 21 of the same year.

Why does a hot air balloon need flame in order to take off?
A Balloon needs hot air to rise, the flame, which is gas burning, heats up the air in the balloon. As Hot air rises above cooler air the balloon takes off.
Is it illegal to build a hot air balloon in your backyard?
If you have children, it should be illegal to have a balloon ready to jump into and take off.
What is compressed air propullsion?
The easiest way to describe compressed air propulsion: Blow air into a ballon (compress the air) then release the balloon. The balloon will take off (propulsion) due to the compressed air within.
When the balloon is up in the air the burner is turned off and the balloon drifts along with the wind What will eventually happen to the air inside the balloon?
The air in the balloon will cool , and the balloon will start to decend.
Why Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
Why does an air balloon float?
If you mean hot air balloon then it floats because hot air rises because it is less dense and with enough hot air caught in the balloon it can lift create enough lift to take off into the air. If you mean a helium balloon then it rises because helium in the balloon is less dense then the air around it. Since less dense things rise to the top the balloon will float.
What make a hotair balloon go up?
Hot air goes into the balloon. sense the air is so hot, it pushes the balloon off the ground and floats in the air!
How do you get off a hot air balloon?
You climb out when the balloon lands on the ground and the basket is secure.
What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
How do air particles create air pressure inside a balloon?
Because the partials are pudding off the balloon it us making it bigger
Does a hot air balloon drop you off where it picks you up?
no
Why does a hot air balloon get off the ground?
because warm gases rise because they are less dense than normal air, so the hot air from the flame is trapped in the balloon thus lifting it off the ground.
