Paper Aircraft Released Into Space

The Paper Aircraft Released Into Space (PARIS) project was a privately organized endeavour undertaken by various staff members of the British information technology website The Register to design, build, test, and launch a lightweight aerospace vehicle, constructed mostly of paper and similar structural materials, into the mid-stratosphere and recover it intact. On 28 October 2010, an aircraft was successfully launched at 90,000 ft (27,000 m)—17 miles up—setting a then world record for "highest altitude paper plane launch" recognised by Guinness World Records at a location about 120 miles (190 km) west of Madrid, Spain.
