For those interested in all things aviation, you might want to visit the Museum of Flight at Boeing Field. They have a nice collection of planes there. Also, Boeing Field is used extensively by Boeing for testing, refurbishment and some finish work. It is common to see aircraft parked in front of the museum, including some military.
Additionally, Saturday is their annual
Helicopter Day.
