Antonov 124s make a regular appearance at Paine Field. Boeing obviously receives a lot of shipments which I am guessing may be engine deliveries. Plenty of the flights come from Columbus OH which is near a GE plant and the GE90-115 fan is too big for most freighters when installed. However, it could be for something else. Anyway, I got one coming in to Everett recently. Paine Field is a popular field for light aircraft so you get a lot of them flying patterns on the main runway. One called up on final when the Ruslan was turning on to final. They made it in without any trouble but it was quite amusing to see the little plane on final with the unmistakable silhouette of the Antonov not far behind.
