...hot air balloons, but what about heavier aircraft?
What is the maximum weight a typical balloon can lift? Could a glider with a gross weight of as much as 1000 lb be carried aloft? And can a ballo...

...timate of o in the above equation. Also, as a general rule, hot air balloons get about 20 lbs (9 kg) of lift per 1000 cu ft (28 cu meters).

The balloon envelope is generally speaking designed to be a fixed size and shape.
Lift is achieved by the simple fact that hot air is thinner (less dense, less weight) than cold ...
