Would you like to take a behind the scenes tour of a working airport before? If not, this may be one for you. This one-hour tour takes you alongside the runways and inside the King County Airport itself. Now, don't get this airport confused with Sea-Tac, this is the airport in Georgetown that is used by private aircraft and planes being produced by Boeing. There is a fee to go on this tour (and it is cheaper if you a member of the Museum of Flight). Participants must be at least 8, and able to board a van on their own. Four tours each Saturday and Sunday during July and August.
