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]
The Ballon Generali is a tethered helium balloon, used as tourist attraction and as an air quality awareness tool. Installed in Paris since 1999 in the Parc André-Citroën, it was created and developed by the French company Aerophile SAS for the celebration of the year 2000. The balloon has lofted more than 500,000 passengers into the sky ...

These balloons are often thicker and have less porosity. [3] Balloons filled with air usually hold their size and shape much longer, sometimes for up to a week.

[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.
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 ...
The balloon handlers were also dressed as Mickey Mouse. 1940s: The parade was canceled from 1942 to 1944 due to rubber and helium shortages during World War II, but it was back on for the rest of ...
