UFOs invading military airspace multiple times a month, but public won't be told
Presumably some or many ufo sightings are highly classified military tests that any random military pilot or radar operator is not ever going know about or even be told about after they sighted it.<p>Its even possible tests are done knowing other military pilots are in vicinity to guage their reaction to it.<p>To me this is the simplest explanation (if weather balloons and drones are ruled out).
