The Boeing 747-8 Intercontinental is followed by a chase plane after taking off on its maiden flight from Paine Field, in Everett, Washington.


Boeing Co's 747-8 Intercontinental, the new passenger version of its legendary jumbo jet, completed its maiden flight without a hitch on Sunday, marking a key milestone for the aircraft model more closely associated with Boeing than any other plane.

The behemoth began its first test flight from Boeing's Paine Field north of Seattle into clear blue skies at 9:58 a.m. local time. The take-off, witnessed by thousands of Boeing employees and aviation enthusiasts, occurred almost 42 years after the first flight of the original 747, which later became one of the most recognized planes in the world.

After almost four and half hours in the air, the red and white plane landed safely at Boeing Field just south of central Seattle.

The 747-8 Intercontinental will seat 467 passengers, 51 more than the current version of the 747. It promises to burn less fuel and offer more passenger comforts. The plane also boasts new wings, a new tail, state-of-the-art engines and a new cockpit.

The 747 was the world's largest airplane until 2005, when Airbus unveiled its 525-seat A380.

Boeing has taken orders for 33 747-8 passenger planes, according to the company website on Friday. The plane lists at $317.5 million.

Germany's Lufthansa has ordered 20 of the planes, and is set to be the first airline to bring the new jumbo into service early next year.

Production of the new 747 has been delayed as has the mid-sized 787 Dreamliner, a carbon-composite plane, which represents a bigger leap in technology than the revamped 747-8.

The stronger-selling freighter version of the 747 has already flown and is due to be delivered in mid-2011 -- 18 months later than first planned. Boeing has sold more than 70 747-8 freighters.

NASA Tests Jumbo Jet With Open Side For Airborne Telescope Observations

These flights will prepare the telescope assembly for the first flight with the telescope operating.


That first flight will be the initial opportunity scientists have to use the telescope and begin the process of quantifying its performance to prepare for SOFIA's planned 20-year science program.


A NASA jumbo jet that will help scientists unlock the origins of the universe with infrared observations reached a milestone Friday when doors covering the plane's telescope were fully opened in flight.

The Stratospheric Observatory for Infrared Astronomy, a modified 747 jet known as SOFIA, flew for one hour and 19 minutes, which included two minutes with the telescope's doors fully opened.

The goal was to allow engineers to understand how air flows in and around the telescope. It was the first time outside air has interacted with the part of the plane that carries the 98-inch infrared telescope.

"We have opened the telescope cavity door, the first time we have fully exposed the telescope and the largest cavity ever flown while in flight," said Bob Meyer, SOFIA program manager at NASA's Dryden Flight Research Center in Edwards, Calif. "This is a significant step toward certifying NASA's next great observatory for future study of the universe."

Besides these test flights of the airplane, two flights to operate and verify the scientific capabilities of the telescope assembly are planned for spring 2010.

Telescope systems such as the vibration isolation system, the inertial stabilization system and the pointing control system will be tested during daytime flights.

These flights will prepare the telescope assembly for the first flight with the telescope operating. That first flight will be the initial opportunity scientists have to use the telescope and begin the process of quantifying its performance to prepare for SOFIA's planned 20-year science program.
SOFIA is a joint venture of NASA and the German Aerospace Center. NASA supplied the aircraft. The telescope was built in Germany.

Dryden manages the SOFIA program. The aircraft is based at NASA's Dryden Aircraft Operations Facility in Palmdale, Calif. NASA's Ames Research Center at Moffett Field, Calif., manages SOFIA's scientific program. The Universities Space Research Association, in Columbia, Md., and the German SOFIA Institute in Stuttgart, Germany, operate SOFIA's scientific program.
