A balloon race that took place in Bremen, Germany, in 2009. A balloon release is a ceremonial event in which a number of hydrogen- or helium-filled balloons are launched into the sky. Balloon releases can be done as a prayer ceremony, to create a photo opportunity, to raise awareness of a cause or campaign, or as a competitive long-distance race.
A look at why there are so many balloons up there — launched for purposes of war, weather, science, business or just goofing around; why they're getting attention now; and how the U.S. is likely ...
Like Walters, Couch had a BB gun on hand to shoot the balloons in order to initiate descent.

[10] [23] During a second flight on July 5, 2008, Couch realized his goal of interstate travel when he landed safely in western Idaho. The ...
The balloon, filled with 6,000 m 3 (210,000 cu ft) of helium, is attached to the ground with a cable, controlled by an hydroelectric winch. This tourist attraction can board up to 30 passengers (this amounts to around 2,500 kg (5,500 lb)) at 150 m (490 ft) above Paris. It is 32 m (105 ft) high, and has a diameter of 22 m (72 ft). [2]
Helium is inert - it does not react with other substances or combust - and its atomic number is 2, making it the second lightest element after hydrogen. Rockets need to achieve specific speeds and ...
It’s widely believed that the suspected Chinese surveillance balloon, shot down by the U.S. military on Saturday after passing over the northern U.S. earlier in the week, was a helium balloon.
The hull of the aerostat contains two parts separated by a gas-tight fabric partition. The upper chamber is filled with helium and provides the aerostat's lifting capability. The lower chamber of the hull is a pressurized air compartment. The hull is constructed of a lightweight polyurethane-coated Tedlar fabric. An airborne engine drives the ...
