Colin Rich constructed a homemade camera-balloon that reached about 24 miles in altitude. The pictures in the above video are breathtaking. And to put a few things in perspective:
(1) The U.S designates people who travel above an altitude of 50 miles (80 km) as astronauts.
(2) 24 miles (126720 ft) is about three times higher than the altitude of most commercial flights.
(3) 25 miles is above 99.95% of the Earth's atmosphere.
