A tethered, moored or captive balloon is a balloon that is restrained by one or more tethers attached to the ground so it cannot float freely. The base of the tether is wound around the drum of a winch , which may be fixed or mounted on a vehicle, and is used to raise and lower the balloon.
Geostationary balloon satellites (GBS) are proposed high-altitude balloons that would float in the mid-stratosphere (60,000 to 70,000 feet (18 to 21 km) above sea level) at a fixed point over the Earth's surface and thereby act as an atmospheric satellite. At those altitudes, air density is around 1/15 to 1/20 [37] of what it is at sea level ...
The highest altitude obtained by an electrically powered aircraft is 29.524 kilometres (96,863 ft) on August 14, 2001, by the NASA Helios, and is the highest altitude in horizontal flight by a winged aircraft. This is also the altitude record for propeller driven aircraft, FAI class U (Experimental / New Technologies), and FAI class U-1.d ...
The launch-point for his jump was from an abandoned runway in Roswell, New Mexico, where he began his gas balloon-powered ascent early that morning. [6] He reached a reported maximum altitude of 135,908 feet (41.425 km; 25.7402 mi), but the final number submitted to the World Air Sports Federation was 135,889.108 feet (41.419000 km; 25.7365735 ...
The US military has shot down a Chinese high-altitude spy balloon in the Atlantic off the eastern coast United States. ... triggering blackouts as it dragged its tether across power lines. As ...
Osoaviakhim-1 was a record-setting, hydrogen-filled Soviet high-altitude balloon designed to seat a crew of three and perform scientific studies of the Earth's stratosphere. On January 30, 1934, on its maiden flight, which lasted over 7 hours, the balloon reached an altitude of 22,000 metres (72,000 ft). [1]
A team of auxiliary U.S. Air Force volunteers launched the paper aircraft from a weather balloon 96,563 feet (more than 18 miles) in the air. It Paper airplane sets world record while flying 82-miles
A favorite part of the festival is the evening Balloon Glow, with tethered balloons lighting up the night skies in Lincoln. Balloon Glow is scheduled for Saturday at 8 p.m. at each launch site.
