He had all necessary licenses and permissions, carried an oxygen supply, ADS-B transponder, and remote control of ballast and balloon-popping squibs. He released himself from the balloons and free-fell until his parachute automatically opened at 7,000 feet (2,100 m). [33] The balloon was then remotely piloted by the ground team to a safe ...
Tethered balloons are used for lifting cameras, radio antennas, electro-optical sensors, radio-relay equipment and advertising banners – often for long durations. Tethered balloons are also used for position marking and bird control work. Typically, they use non-flammable helium gas to provide lift.
Balloon rockets work because the elastic balloons contract on the air within them, and so when the mouth of the balloon is opened, the gas within the balloon is expelled out, and due to Newton's third law of motion, the balloon is propelled forward. This is the same way that a rocket works.
The US Army built the first helium extraction plant in 1915 at Petrolia, Texas, where a large natural gas field averaged nearly 1 percent helium. [6] The United States Navy established three experimental helium plants during World War I, to recover enough helium to supply barrage balloons with the non-flammable, lighter-than-air gas. Two of the ...
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]

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.
The 1785 Rozière balloon, is the main type of hybrid balloon, named after its creator, Jean-François Pilâtre de Rozier. It has a separate cell for a lighter-than-air gas (typically helium), as well as a cone below for hot air (as is used in a hot air balloon) to heat the helium at night.
