ABSTRACT:
An airborne, free floating, lift-weight, balanced balloon having a closed envelope encompassing a fixed volume of lighter-than-air gas has ballast means fixed on the bottom of the envelope to tend to balance the weight of the balloon to equal the lifting effect of the gas, and to tend to cause the balloon to float in a desired horizontal attitude. At least one ballast member or a pair of ballast members form part of the ballast means and are fixed to the bottom of the balloon in symmetrical relationship to a vertical plane passing through the central horizontal axis of the balloon, ballast member(s) being constituted as a plurality of pressure sensitive removable weight control modules also arranged symmetrically with respect to a vertical plane passing through the central horizontal axis of the balloon when the balloon is in its desired attitude. These weight control modules are removed one or two at a time in order to balance the weight of the balloon so that it will float at a desired altitude. These weight control modules are removed from locations on the skin of the balloon such that the desired attitude of the balloon will be maintained or reestablished.
