While we're wanking over balloons, anon was reminded of weird story from Brazil some years ago.
Fatal cluster ballooning (fuck) attempt
On April 20, 2008, after taking off in a chair attached to 1,000 balloons, Carli reached an altitude of 6,000 metres (19,700 ft) before losing contact with authorities. Pieces of balloon were later reported floating in the sea off the coast.
Carli's flight equipment included a parachute, helmet, waterproof coveralls, GPS device, mobile phone, satellite phone, flotation device chair, aluminum thermal flight suit, and at least five days of food and drinking water. His training for the stunt included jungle survival and mountain climbing courses, but apparently did not include instruction on the use of his GPS navigation device. On April 20, the priest's last contact with the military police occurred during the night, when he was about 16 miles from the islands of Tamboretes, off the coast of São Francisco do Sul, Santa Catarina, Brazil. The priest called from his cell phone to request help determining his coordinates and to ask them to contact the authorities. Two days after the flight, a Penha (SC) Fire Department commander familiar with the situation put the missing priest's chances of still being alive at 80%. The Brazilian Navy called off the ocean search on April 29, saying the chances of finding de Carli alive in the ocean were "very remote".
