Here's pictures from an observation point @ Incheon Airport @ Seoul, South Korea I took last month. As you can see, it's much farther away from the runway than Imperial Hill but since without a car, I couldn't get to the better spotting locations. It was pretty hazy that day and there was a lot of heat haze as well. Lots of KAL and Asiana planes all day.
