General
Seattle-Tacoma International Airport, or Sea-Tac as it commonly called, was developed as a direct response to the Japanese attack on Pearl Harbor on December 7, 1941. Initial construction was completed in October 1944, but full civilian operation did not commence until dedication of a modern terminal building on July 9, 1949. Sea-Tac officially became the Seattle-Tacoma International Airport on that day.
Layout
Sea-Tac features three parallel, north-south, runways. The passenger terminal is located near the south-eastern side of the airport along side State Route 99. In the same area, the Delta and Alaska Airlines hangars can be found. A small bizjet terminal is located between the runway 34L and 34C tresholds. Cargo aprons are mainly located on the north-eastern side of the airport.
Getting There
The airport is located at the intersections of State Route 518, State Route 99 and State Route 509, about 2.4 km west of Interstate 5.

Spot 6 is great for landing shots during the afternoon. If you are creative, you could even take pictures with Mt. Rainier in the background. (Leo Hoogerbrugge)
