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]
Do not use metallic ribbon with helium-filled balloons; Although the law was put into effect in 1990, the issue of foil balloons being a hazard resurfaced in 2008. A senate bill was proposed to ban the sale of all foil balloons by the year 2010 due to the increased number of power outages. [citation needed] The bill was California Senate Bill 1499.
Tethered Aerostat Radar System in New Mexico. The first aerostats were assigned to the United States Air Force in December 1980 at Cudjoe Key, Florida. During the 1980s, the U.S. Customs Service operated a network of aerostats to help counter illegal drug trafficking. Their first site was built at High Rock, Grand Bahama in 1984.

A dozen or so hot air balloons, some 1,600 feet above ground level, scattered a sky that soon would fill with hundreds of more balloons for the 52nd Albuquerque International Balloon Fiesta.
Since both ballast and gas are finite, there is a limit to how long a variable-volume balloon can compensate in order to stabilize its altitude. In contrast, a superpressure balloon experiences smaller changes in altitude without compensation maneuvers. [2] Because the volume of the balloon is more constrained, so is the volume of air displaced ...
Ed Yost redesigned the hot air balloon in the late 1950s using rip-stop nylon fabrics and high-powered propane burners to create the modern hot air balloon. His first flight of such a balloon, lasting 25 minutes and covering 3 miles (5 km), occurred on 22 October 1960 in Bruning, Nebraska. Yost's improved design for hot air balloons triggered ...
