Two different commercial airline pilots reported seeing an unidentified aircraft in the skies above Arizona in February, according to new radio logs released by the FAA.

According to the recordings, first revealed by Warzone writer Tyler Rogoway, and subsequent statements, the unidentified aircraft was first spotted by an American Airlines pilot at the helm of a Learjet at around 3:30 p.m. on February 24th. With no other aircraft visible on radar, the pilot radioed to the regional air traffic controller in Albuquerque to report the sighting.

Was anybody, uh, above us that passed us like 30 seconds ago?” the Learjet pilot can be heard asking air traffic control.

“Negative,” the air traffic controller replied.
