    en.wikipedia.org/wiki/Lawnchair_Larry_flight

    Cluster ballooning was inspired by Larry Walters's experience, although his was not the first. [1]On July 2, 1982, Larry Walters (April 19, 1949 – October 6, 1993) made a 45-minute flight in a homemade aerostat made of an ordinary lawn chair and 42 helium-filled weather balloons. [2]

    A Helikite lifting a gyro-stabilized camera. The Allsopp Helikite is a kite balloon or kytoon designed by Sandy Allsopp in the United Kingdom in 1993. [1] This Helikite comprises a combination of a helium balloon and a kite to form a single, aerodynamically sound, tethered aircraft, that utilises both wind and helium for its lift.

  4. High-altitude balloon - Wikipedia

    en.wikipedia.org/wiki/High-altitude_balloon

    High-altitude balloons or stratostats are usually uncrewed balloons typically filled with helium or hydrogen and released into the stratosphere, generally attaining between 18 and 37 km (11 and 23 mi; 59,000 and 121,000 ft) above sea level. In 2013, a balloon named BS 13-08 reached a record altitude of 53.7 km (33.4 mi; 176,000 ft). [1]

  5. Cluster ballooning - Wikipedia

    en.wikipedia.org/wiki/Cluster_ballooning

    Cluster ballooning is an extreme sport and a form of ballooning where a harness attaches a balloonist to a cluster of helium-inflated rubber balloons. Unlike traditional hot-air balloons , where a single large balloon is equipped with vents enabling altitude control, cluster balloons are multiple, small, readily available and individually ...

    en.wikipedia.org/wiki/Rozière_balloon

    During 1999, Bertrand Piccard and Brian Jones achieved the first non-stop balloon circumnavigation in Breitling Orbiter 3, a Rozière balloon. A Rozière balloon (or simply Rozière) is a type of hybrid balloon that has separate chambers for a non-heated lifting gas (such as hydrogen or helium) as well as for a heated lifting gas (as used in a hot air balloon or Montgolfière). [1]

  7. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    A balloon can only have buoyancy if there is a medium that has a higher average density than the balloon itself. Balloons cannot work on the Moon because it has almost no atmosphere. [15] Mars has a very thin atmosphere – the pressure is only 1 ⁄ 160 of earth atmospheric pressure – so a huge balloon would be needed even for a tiny lifting ...

  8. Helium - Wikipedia

    en.wikipedia.org/wiki/Helium

    According to helium conservationists like Nobel laureate physicist Robert Coleman Richardson, writing in 2010, the free market price of helium has contributed to "wasteful" usage (e.g. for helium balloons). Prices in the 2000s had been lowered by the decision of the U.S. Congress to sell off the country's large helium stockpile by 2015. [23]

  9. History of military ballooning - Wikipedia

    en.wikipedia.org/wiki/History_of_military_ballooning

    Balloons and kites were the first inventions used in aerial warfare and their primary role was reconnaissance. Balloons provided a reliable and stable means of elevating an observer high over the battlefield to obtain a birds-eye view of troop positions and movements. An early instrument of aerial intelligence collection, they were also useful ...
