It looks like United Express will begin flying from SEA to MWH (only around 30 min away from the Silo) starting June 4th. Round trip flights between SEA and MWH are currently ranging ~$170-$180 but you should be able to book tickets directly to MWH through SEA. We're currently looking into providing a shuttle service between MWH and the Silo during some of the days. For now, if you're flying to MWH, please post your flight info to the Rideshare forums so we can plan our shuttle sizes and bus pickup times accordingly.
