This would make the inside and outside air pressures equal. "Balloons." Who invented mylar balloons?
However, since this is near impossible to measure, air pressure seems to be easier described as density. The BoPet film was developed by DuPont, Hoechst, and Imperial Chemical Industries (ICI) in the 1950s. Once released, the balloons fall onto their target area below.
Also in the 1950s at the start of the Cold War, activists in Western Europe uses balloons for propaganda purposes that would float east over Eastern Europe, which would release newspapers and pamphlets.
