Additionally, the team improved the aircraft’s landing system following Phantom Eye's first flight, when the landing gear dug into the Edwards lakebed and broke. The improved landing system is based off Boeing's fighter aircraft systems.
Phantom Eye's liquid-hydrogen propulsion system will allow the aircraft to stay on station for up to four days while providing persistent monitoring over large areas at a ceiling of up to 65,000 feet, creating only water as a byproduct. The demonstrator, which features a 150-foot wingspan, is capable of carrying a 450-pound payload. Its first flight, in coordination with NASA's Dryden Flight Research Center at Edwards, was in June 2012.
