There may actually have been a legitimate reason for that. First, not all these "things" are said to be flying, some are supposed to have gone underwater (although "Aerial" sort of wrecks that idea). Second (and IMO more important), "Object" (in UFO) begs the question of whether these are objects. Many of them are not--they're artifacts in imaging or radar systems, or optical illusions--perhaps intentional illusions. ("Things" that appear to be moving really fast, then take a sudden turn, are easily imitated by lines of drones carrying radar and/or visual transponders.)
