The age of the UFO has vanished into outer space, but back in the '50s and '60s many reputable reported strange lights, zooming lights, etc. to the CAB and then to its FAA successor.
Some of the grillings they received by federal officials during "interviews" were like the good cop, bad cop routine. They were told to fly the plane and leave UFOs and strange lights to the Air Force. The word got out of their good but frowned at intentions and they stopped reporting strange sightings.
Could it be that in today's security climate, the feds are not interested in what a "lowly" pilot thinks. Change it around a bit and the feds may be saying, "leave the gum shoe work to the cops. They're trained for it. You're not."
If I was the FBI or the TSA I would welcome American Airlines data base, but unfortunately I'm not.
