I diverted my Sunday outing (not far admittedly and I wasn’t under any pressure to be anywhere at a given time) when I saw that an IAero 737 was coming into SEA. This is a 737-300 which means it isn’t too common anymore. There was a time when these things were everywhere. Southwest had tons of them and this example was one of theirs. The conditions were a bit overcast so not ideal but with the sun angle being on the nose, having some cloud made things a little easier. They were bouncing around on short final.
