The only limit to human flights was King Louis XVI who had forbidden them to make such a flight, as he felt responsible for his subjects' lives. After long negotiations, he accepted to give permission to it but refuse to be personally there. The Montgolfier brothers did not fly themselves as they had promised their father never to fly in their balloon as he was not personally convinced of the security offered by their invention. Pilâtre de Rosier was chosen for the flight. An other passenger participated to the flight to balance the basket. The basket was divided into three parts: the two lateral parts were reserved for the passengers. The burner (a fire made of straw) was in the one of the centre of the basket. Additionally, the passengers could feed the fire with straw to control the balloon altitude. The flight took place on 21st of November 1783, a date which would entered in History. In fact, it appears that Pilâtre had a very developed sense of piloting the balloon. He felt with a accuracy when the balloon had to be heated and when not when Sir d´Arlanes behaved in a much more passive way. The result of this was they succeeded in flying above Paris during 28 minutes approximately. Their flight altitude reached 3.000 feet.

What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
If you were to turn on the burner on in the hot air balloon what effect would it have on the air in the balloon?
When the burner on a hot air balloon is turned on the air inside the balloon is heated making it less dense. This will cause the balloon to be more buoyant and climb.
What is the importance of the burner in a hot air balloon?
If the burner fails or runs out of fuel, the hot air in the balloon (that gives it lift) would cool and the balloon would come down to earth.
Who invented a famous burner?
Bunsen burner: invented by Robert Bunsen, German chemist Mekerburner: invented by Geoges Meker, French chemist Teclu burner: invented by Nicolae Teclu, Romanian chemist
Who invented the Bunsen burner and what it was invented to do?
This burner was invented by Bunsen or more probable by Desaga; the scope is to be a source of heating in the laboratory.
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 must hot air balloon pilots do occasional blasts on the burner?
To keep the hot air flowing in the balloon.
How do balloonists make the balloon descend gradually?
The balloonist would turn of their burner so that the balloon can lose its latitude and then gradually the balloon will come down.
How does balloon flight work?
By using a heat burner, hte balloon pilot makes the air in the balloon lighter than normal air. Then the balloon moves upward and moves with the wind.
How does a balloon pilot control BOTH acsent and descent of a balloon?
A balloon pilot controls ascent by heating the air inside the balloon with a burner and descent by allowing the air to cool or venting it.
Why does a gas burner in a balloon begin to rise when heated air is trappd inside the balloon?
The hot air from the gas burner rises and enters the balloon's envelope. Once there is enough hot air trapped, the whole balloon will begin to lift off the floor. This is due entirely to the fact that hot air rises.
What gas do we fill in hot air balloon?
Hot air balloons are filled with hot air from a propane burner in the basket. Hot air rises. So provided the cooling air in the balloon is topped up from short blasts from the burner, the balloon will rise off the ground.
