Project Icarus was an experiment in 2009 to launch a camera into the stratosphere undertaken by MIT students, Justin Lee and Oliver Yeh. [1]The launch vehicle consisted of a weather balloon filled with helium and a styrofoam beer cooler that hung underneath the balloon.
The inhalation from larger helium balloons has been reportedly fatal. [26] A fatal fall from a tree occurred after the inhalation of helium from a toy balloon, which caused the person to become either unconscious or lightheaded. [27] In 2015, a technician at a health spa was asphyxiated while conducting unsupervised cryotherapy using nitrogen ...
Balloon Experiments with Amateur Radio (BEAR) is a series of Canadian-based amateur radio high-altitude balloon experiments by a group of amateur radio operators and experimenters from Sherwood Park and Edmonton, Alberta. The experiments started in the year 2000 and continued with BEAR-9 in 2012 reaching 36,010 metres (118,140 ft).
Project Excelsior was a series of parachute jumps made by Joseph Kittinger of the United States Air Force in 1959 and 1960 from helium balloons in the stratosphere.The purpose was to test the Beaupre multi-stage parachute system intended to be used by pilots ejecting from high altitude.
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]
The Antarctic Impulsive Transient Antenna (ANITA) experiment has been designed to study ultra-high-energy (UHE) cosmic neutrinos by detecting the radio pulses emitted by their interactions with the Antarctic ice sheet. This is to be accomplished using an array of radio antennas suspended from a helium balloon flying at a height of about 37,000 ...

Trappe continued to experiment in cluster ballooning flights. In 2011, he replicated the floating house from the animated film Up for a National Geographic television program. [28] On July 6, 2015, Daniel Boria of Calgary, Alberta, Canada, tied about 100 helium balloons to a garden chair and flew over his city in a publicity stunt.
