EVERETT, Wash.--Sunday marked the first flight of Boeing's all-new 747-8 Intercontinental. Billed as the aviation giant's biggest-ever passenger plane, as well as its most fuel- and cost-efficient, the plane will be the only one in the 400- to 500-passenger market.
Boeing unveiled the plane at a giant ceremony at its plant here last month, and on Sunday, the plane took off for its first flight.
It is expected to land at Seattle's Boeing Field after at least a couple of hours aloft.
Hanging from the tail of the plane is a trailing cone, which, when it is in the air, can go out to between 150 and 200 feet behind the plane. The cone is meant to measure the difference between total pressure and static pressure in order to figure out altitude and total airspeed.
