there is a rope, much like the rope truckers pull for their horns, that you pull down, opening a flap on the top,letting the warm air out. this allows them to float back to earth...
By releasing some of the hot air in a very controlled manner.
What they do is blast cold air into the "hot" air and it makes the air molecules slow down... Thus it makes the air balloon decrease back to earth.

Hot air balloon pilots use propane to heat their balloons. It's inexpensive, very easy to obtain, and works.
Escaped balloons can only rise to the altitude where they are the same density as the surrounding air; they cannot go into space. Eventually the helium leaks out and they fall back down.
a hot air balloon only works using thermals, which are currents of hot air rising because one area is heated more than the others. so hot air balloons depend on air to keep it airborne, specifically hot air. once it leaves the earths atmosphere, it is a vacuum. there is no air, so the hot air balloon will fall back into the earth. hence, we see that hot air balloons cannot leave the earth's atmosphere.
Yes, navy pilots and air force pilots are military pilots.
In the United States, a pilot of a hot air balloon must have a pilot certificate from the FAA and it must carry the rating of "Lighter-than-air free balloon", and unless the pilot is also qualified to fly gas balloons, will also carry this limitation: "Limited to hot air balloons with airborne heater". A pilot does not need a license to fly an ultralight aircraft, but training is highly advised, and some hot air balloons meet the criteria. To carry paying passengers for hire (and attend some balloon festivals), a pilot must have a commercial pilot certificate. Commercial hot air balloon pilots may also act as hot air balloon flight instructors. While most balloon pilots fly for the pure joy of floating through the air, many are able to make a living as a professional balloon pilot. Some professional pilots fly commercial passenger sightseeing flights, while others fly corporate advertising balloons.
air balloons or hot air balloons fly because they fill with a very light type of air. The air is hot air.
Hot air is used for hot air balloons.
Escaped balloons can only rise to the altitude where they are the same density as the surrounding air; they cannot go into space. Eventually the helium leaks out and they fall back down.
