Boeing unveils new spy plane..

Be Wary... Be very Wary... You are being watched :O)
Boeing has unveiled an unmanned hydrogen-powered spy plane called Phantom Eye which can fly for days on end without refuelling.
The aircraft is designed for endurance reconnaissance missions, soaring at 65,000ft for up to four days.
The “green” vehicle’s two 2.3-litre Ford engines provide 150 horsepower each, allowing it to cruise at 150 knots without producing any harmful emissions.
Unveiling the plane in St Louis, Darryl Davis, president of Boeing Phantom Works, said: "Phantom Eye is the first of its kind and could open up a whole new market in collecting data and communications.
“The capabilities inherent in Phantom Eye's design will offer game-changing opportunities for our military, civil and commercial customers."
“The hydrogen propulsion system will be the key to Phantom Eye's success,” said Drew Mallow, Phantom Eye program manager. “It is very efficient and offers great fuel economy, and its only by-product is water, so it's also a 'green' aircraft."
