Huge Plane Is Heavier, Thirstier, Later Than Projected
It's not unusual for a new aircraft built with composite
technology to have production fall behind schedule. But Boeing's
747-8 is a variation on the 747 theme that dates back more than 40
years, stretched to carry up to 467 passengers. The longer version
uses of new wings and engines, but has wound up a year behind
schedule, an estimated eight-11 tons overweight, and less
fuel-efficient than projected.
