By 1958, the Fulton aerial retrieval system, or "Skyhook", was finished. The ground system could be dropped from an aircraft and contained the necessary equipment for a pickup, including a harness, for cargo or a person, attached to 500 feet (150 m) of high-strength, braided nylon line and a dirigible-shaped balloon inflated by a helium bottle.
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 Balloon Boy hoax occurred on October 15, 2009, when a homemade helium-filled gas balloon shaped to resemble a silver flying saucer was released into the atmosphere above Fort Collins, Colorado, by Richard and Mayumi Heene. They then claimed that their six-year-old son Falcon was trapped inside it.
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]
Explorer II was a crewed U.S. high-altitude balloon that was launched on November 11, 1935, and reached a record altitude of 22,066 m (72,395 ft). Launched at 8:00 am from the Stratobowl in South Dakota, the helium balloon carried a two-man crew consisting of U.S. Army Air Corps Captains Albert W. Stevens and Orvil A. Anderson inside a sealed, spherical cabin.
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 ...
