From Seattle Times:
The big moment had arrived and the crowd watched in excitement: Mark Kirsch, strapped to a Boeing 767, was about to drag the 200,000 pounds of metal and fuel down the runway at Boeing Field.

He pulled and he pulled, the Saturday crowd's anticipation rising, his muscles bulging — then the strap broke. And strongman Kirsch went stumbling.

So he tried again, but the plane wouldn't budge.

"Well, so much for that," groaned a man in the crowd.

While the festivities got off to a rocky start at the 80th anniversary celebration of Boeing Field, that didn't keep scores of people from enjoying a sunny day at the Seattle airport.

The site, originally cleared for farming, was officially made an airport in 1928. In its early years, the King County facility was used by the postal service as a major hub for moving packages between Seattle and Los Angeles. During World War II, Boeing used it to build B-17 and B-24 bombers.

Today, the airport handles some 300,000 takeoffs and landings a year, for commercial and business aviation along with aircraft production.
