Both happened on islands that are in Puget Sound, however Whidbey Island is way north of Seattle, and Ketron Island involved with the plane yesterday is way south of Tacoma, in the vicinity of Steilacoom.
Near Ketron Island is Anderson Island, people say this was a location in the film War Games. It is also near Fox Island, where Governor Dixie Lee Ray lived back in the 80's, and McNeil Island, home of a now closed corrections center.
