ST. LOUIS, March 8, 2010 -- The Boeing Company [NYSE: BA] has begun to build Phantom Eye -- its first unmanned, liquid-hydrogen powered, high altitude long endurance (HALE) demonstrator aircraft.

“The essence of Phantom Eye is its propulsion system,” said Darryl Davis, Boeing Phantom Works president. “After five years of technology development, we are now deploying rapid prototyping to bring together an unmanned aerial vehicle [UAV] with a breakthrough liquid-hydrogen propulsion system that will be ready to fly early next year.”

Phantom Eye’s entire propulsion system -- including the engine, turbo chargers and engine control system -- successfully completed an 80-hour test in an altitude chamber on March 1, clearing the way for the propulsion system and UAV to be assembled.

The twin-engine Phantom Eye demonstrator will have a 150-foot wingspan and be capable of flying for more than four days at altitudes up to 65,000 feet while carrying a payload of up to 450 pounds. Phantom Eye is designed to maintain a persistent presence in the stratosphere over a specific area, while performing missions that could include intelligence, reconnaissance, surveillance and communication. Boeing also is developing a larger HALE that will stay aloft for more than 10 days and carry payloads of more than 2,000 pounds, and building “Phantom Ray,” a fighter-sized UAV that will be a flying test bed for advanced technologies.

The Federal Aviation Administration is investigating how a child was allowed to direct air traffic at the nation's sixth-busiest airport - New York's JFK International.

As CBS News Correspondent Kelly Wallace reports, the Feb. 17 incident involved a child on the radio to pilots of planes awaiting takeoff. The boy was allowed to make at least five transmissions to commercial jets.

In a statement, the FAA says, "Pending ... our investigation, the employees involved in this incident are not controlling air traffic. This behavior is not acceptable and does not demonstrate the kind of professionalism expected from all faa employees."

The FAA confirms to CBS News that the two employees who have been suspended are the controller who brought his son into the tower (the FAA confirms it is his voice on the recording) and the supervisor who “tolerated” the incident.

The pilot of a plane which crashed into an office block in Austin, Texas, left a note expressing his anger at federal tax authorities, police say.

Police are linking the apparent suicide note left online to Joseph Andrew Stack, the man named as the pilot.

The note criticised the Internal Revenue Service - based inside the office block and declared: "Violence is the only answer."

Firefighters continue to search for one person who is still unaccounted for.

With their new Piper Cub, A2A has, if nothing else, proven their versatility. They have gone from the biggest engines and airliners of World War II to this small yet incredibly important little aircraft. I needn’t describe the Cub’s history or how many aviators earned their wings in the Cub, but from my point of view it provides an opportunity for A2A to show how much can be done in the simulator; they’ve proven what they can do with systems and engines, and now it’s a chance for them to show what can happen with one of the most basic relationships between man, plane, and sky.
