They are unrelated. I was just at BFI (Boeing Field) and saw a 737 (-500?) with winglets. It was bare metal, but there was a reg number: N128QS. Anyone have info on this one?
My other question is for any of the strikers. I noticed the plane spotting seems to be better on that side of the field. Will I be harassed too much if I just go there to plane spot? Thank you!
