Cluster balloon flights
Couch, a 47-year-old gas station owner, first flew 193 miles (311 km) in July 2007 riding a lawnchair elevated by 105 large helium balloons. Using amateur instruments to measure altitude and speed, a GPS device to track his location, and 5 gallons (19 litres) of water for ballast, he controlled his descent by releasing water. The flight began in Bend, Oregon and ended in Union, short of Couch's goal of reaching Idaho.
Couch's flight resembled the Lawnchair Larry flight. Larry Walters in 1982, sat in a lawnchair that unexpectedly rose 3 miles (5 km) off the ground after he cut the rope tethering the chair to the ground.
