KSEA Sea-Tac Arrival & Tower Journey

Overview

Located at 600ft MSL near waypoint WOODI (King/Snohomish border), this station is optimized to capture the complete "journey" at KSEA Sea-Tac. This stream follows the narrative of a flight from high-altitude handoffs, to intermediate vectoring, final approach, touchdown, and across the tarmac. Some KBFI, KPAE traffic is also on this feed.

By listening to this feed with my Stratosphere & Enroute feed, you can listen to many of the in-flight commercial aircraft comms in over a 100 mile radius of Seattle.
