The Seattle area badly needs another airport. Sea-Tac is close to being maxed out. The Legislature is studying the issue with a goal towards having a new airport ready to receive passengers by 2040 (!). One of the possibilities being looked at is the Moses Lake airport, a former SAC bomber base 180 miles east of Seattle. In order to transport passengers from the west side of Washington to the airport, a high speed passenger train tunneling through the Cascades (!) is being considered. I am pretty sure that the billions of dollars this will cost will remove Moses Lake from the list of airport candidates.
