Best Answer: A tethered hot air balloon flight will typically be between 50-75 feet. It's high enough for the passengers to get a feel for the height and manageable enough for rope length. I have heard of some gas ride balloons that are on a winch go higher. To tell you the truth, I can't recall the max height for tethering. It wouldn't be different than for gas balloons.
The air inside of the balloon has weight too. A cubic foot of air weighs .078125 pounds. A medium size balloon will hold 90,000 cubic feet of air and suddenly you have 7,031 pounds of air mass to contend with. This mass does not include such things as the aerodynamic load on the balloon, the weight of the balloon system itself, or the passengers and crew.
