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.
However, the air was so thin and the temperature was so low (12 Â°F) that they were unconscious when they reached that altitude. In May, 1961, the current official altitude record was set. Commander Malcolm Ross and Lieutenant Victor A. Prather, Jr. of the US Navy rose 113,740 feet (34,668 m). The name of the balloon was USN Strato-Lab V. This flight was part of a program called Strato-Lab which used experimental high-altitude manned plastic balloons. Prather drowned and died after his Strato-Lab V flight. His pressure suit filled with water as he landed at sea after his record breaking flight. Even though the highest altitude was 34,668 meters, according to the McGraw-Hill Encyclopedia of Science and Technology, a zero-pressure balloon is capable of rising to an altitude of 140,000 feet (42,000 m).
