Robert Best, Everett Herald publisher, and Petrie pitched the airport to Boeing president Bill Allen, who interrupted them. “He said they had already optioned about 700 acres. Bob and I looked at each other in amazement,” Petrie told the Herald. “He had no idea Boeing was thinking that big.”

Dozens of cars and a new building under construction at Paine Field, date unknown. Local officials pledged to do whatever was needed to land the factory, which Boeing expected would employ about 15,000 people. Today, roughly 40,000 people work at the sprawling plant and office buildings.

Aug. 4, 1981, was a memorable day for Boeing. The company’s first new commercial transport in more than a dozen years, the Boeing 767, rolled out of the Everett plant in front of 15,000 onlookers. This widebody airplane was the first of a new generation of Boeing commercial transports designed for the fuel-conscious 1980s. Using the latest technology, the 767 promised to burn 30 percent less fuel than the generation of transports it was replacing. (Photo courtesy The Boeing Co.)

The first production model of the new Boeing 787 Dreamliner airplane is unveiled to an audience of several thousand employees, airline executives and dignitaries during a ceremony on July 8, 2007, at Boeing’s assembly plant in Everett. The 787 is Boeing’s first all-new plane since airlines started flying the 777 in 1995. Boeing has already booked more than 600 orders for the plane, which is promised to burn less fuel, be cheaper to maintain and offer more passenger comforts than comparable planes flying today.
