That being the case, when he sees something that is truly unidentified, he's pretty sure it's not a super-secret military project. And he has seen some unusual things. I'm just one of 15,000 controllers, too, so there have to be many more that go unreported. On one occasion, he saw another controller discuss a UFO incident with his supervisor. The controller told the supe about the encounter, and after both determined there was nothing on radar, they just kind of shook their heads and rubbed their chins, and that was that.
Nobody knows what to do, really.
There is no government 'coverup,' no mirror-sunglassed agents 'debriefing' us in the back room, no military specialists to take reports. But 'UFO' encounters happen. I've been puzzled on all three. I got on the landline to the lower controller to warn him for subsequent aircraft. We just shook our heads, and mostly forgot about it, though the pilot did make a report on it and it appeared in Aviation Week and Space Technology.
