This is...Certainly the last place I'd expect there to be a cache! Also never knew Seattle had a museum of flight!
Geocaching
Geocaching is a worldwide scavenger hunt that uses a GPS or phone app with GPS. There are over 3 million active caches around the world. Some are as small as a dime, others are big enough to walk into, all of them provide a unique adventure. We invite you to share your stories, photos, and experiences!
Haven't been yet, but being right next to Boeing's main plant, you better believe it looks cool.
Hell, it's so big you can see the museum as your plane comes in for a landing at SeaTac.
A geocache and a museum, sounds like a win win situation
There was a cache near me which was hidden in a tea house. You had to go up to the cashier and ask for the cache. Thought that was pretty cool.
There is a flight simulator in the museum that moves as you fly. Pro tip: You don't have to follow the flight plan in the simulator. My buddy did barrel rolls and loops until the time ran out. Everyone after him in line did the same thing.
I'm not sure if they let you do that anymore. He has a history of having signs/rules made in places after he does something they don't specifically have rules against.
