History of Ballooning - 20th Century

20th Century

During World War II, a large number of barrage balloons were inflated over the city of London in an effort to obstruct Luftwaffe air attacks during the Battle of Britain. Whatever their effectiveness, they were a cheap defense but did not stop heavy damage inflicted on Londoners during the Blitz, probably because the Heinkel He 111 bombers flew too high. Nonetheless, some 231 V-1 flying bombs were destroyed.

In the early and mid-20th century, hydrogen balloons were used extensively in upper-atmosphere research in such projects as Osoaviakhim-1, the Stratobowl launches, Project Manhigh, and Project Strato-Lab. A series of ascensions set a number of high-altitude records before space flight eclipsed ballooning as an endeavor. When governments lost interest in manned balloons, private citizens continued to strive to set records, especially for long distances, and to achieve "first" marks (such as Double Eagle II (first to cross the Atlantic Ocean) and Breitling Orbiter 3 (first to circumnavigate the world).

Although manned high-altitude balloon ascensions are still undertaken, they are more likely to be the work of adventurers than researchers.
