The growing worldwide demand for air travel during the 1960s led to the development of the 747, the first "Jumbo Jet." Merely recalling the early days of the 747 program "brings sweat to the palms of my hands," Boeing's then-president, William Allen, said years after the giant aircraft had been developed. Requiring the company to risk much of its net worth, the development of the world's largest passenger aircraft was a formidable undertaking. It is taller than a six-story building, has seating for 374 passengers (up to 550 in some configurations), a takeoff weight of more than 300 tons (or ten fully-loaded 18 wheel trucks), and enough fuel in its tanks to power a small automobile around the globe 36 times. The 747 is one the most recognizable aircraft in the world and represents a milestone in the evolution of aviation design.

The Museum's aircraft was the first 747 ever built - serial number 001. It first flew on February 9, 1969 over Western Washington. Later, this aircraft served as a testbed for 747 systems improvements and new engine developments for other Boeing commercial jets, including the state-of-the-art Boeing 777 engine program.
