Answer: to a problem faced by the military: the need for a large, long-range aircraft that could transport cargo and personnel to remote locations. The Pelican, also known as the Phantom Eye, is a high-altitude, long-endurance unmanned aerial vehicle (UAV) developed by Boeing. The design process for the Pelican began in early 2000, when designers in the Phantom Works division of Boeing started working on a solution to the military's need for a large, long-range aircraft that could transport cargo and personnel to remote locations. The Pelican is designed to fly at high altitudes, where the air is thin, and it uses liquid hydrogen as a fuel. It can fly for up to four days at a time, and it has a range of more than 2,000 miles. The Pelican was designed to be a surveillance aircraft, but it can also be used for other applications such as communications relay and atmospheric research.
