Plane spotting is best practiced on terra firma. Still, plane spotters’ knowledge goes where they go—and nothing will grab the attention of two spotters flying the traffic pattern in a Cessna 172 like the tower saying, “Make short approach. Your traffic is a Galaxy on a two-mile final.” Landing and (promptly) taxiing clear, the plane spotters check how closely the huge C-5 was trailing, only to see a mid-sized bizjet touching down. Did somebody cut in? No. This is a Gulfstream G200, named after its original manufacturer, Galaxy Aerospace.
