HIAPER will provide scientists with insights into the atmosphere and EarthÕs natural systems. A modified Gulfstream V jet, the aircraft can fly at an altitude of 51,000 feet and has a range of 7,000 miles. It can carry 5,600 pounds of sensors, putting it on the forefront of scientific discovery. HIAPER will collect data at the tops of storms and lower edge of the stratosphere, altitudes out of reach of most research aircraft. The aircraftÕs range will enable scientists to survey remote ocean regions in a single flight to learn more about interactions between the oceans and atmosphere.
