planespotter
n.— «In addition to its FAA flight history, the Gulfstream has been tracked, and sometimes photographed, by the worldwide cadre of aviation aficionados who call themselves “planespotters”—not because of its possible connection with the U.S. government, but because planespotters pride themselves on keeping meticulous records of every aircraft that comes and goes at their chosen airports.» —“Jet’s travels cloaked in mystery” by John Crewdson, Tom Hundley Kansas City Star (Mo., Kan.)
