Balloons travel with the wind, so all their motion over ground comes from air movements. do hot air balloons have the ability to control their ground speed? If so, how? This was a burning question in the nineteenth century and many attempts were made to influence ground speed, apart from rising into higher altitudes and testing whether the wind direction ...

An ordinary hot-air balloon drifts with the wind and so its ground speed is always that of the wind. Some control over flight direction is possible by knowing or guessing the wind direction at different altitudes and climbing or descending to a level where the wind is favourable. A hot-air "dirigible balloon" or airship has an engine and propeller. ...

The only horizontal forces which act on hot air ballons are that of drag because of wind. In other words, balloons are pushed around only by wind. There is no other horizontal force (e.g. motor, or other means of propulsion) which act upon the balloon. This means that as soon as the balloon reaches the wind velocity, it will not feel any other horizontal ...

A hot air balloon has no means of (horizontal) propulsion. As such, it will not move relative to the surrounding medium (the air). If the air moves relative to the ground (wind), the balloon will remain stationary relative to the air, and thus also move over the ground. In other words, if the wind is blowing at 10 knots, the balloon will have a ground speed ...
