Elliot Chang writes "Targets of espionage beware! Planemaker Boeing just unveiled its new hydrogen-powered spy plane yesterday, and the strangely cute and chubby aircraft is capable of flying at an altitude of 65,000 feet for a period of four straight days. Called the Phantom Eye, it will be able to travel at 150 knots (170 miles per hour) and has two 2.3 liter, four-cylinder engines, each of which provide only about 150 hp (about the same as an average car). The Phantom is one of the greenest planes out there since its only byproduct is water!"
