The new episode "Airline Encounters" relates how American airline pilots have reported mid-air near-collisions with unidentified flying objects. Luis Elizondo hears an eyewitness account from a major legacy airline pilot who says he saw a glowing orange sphere from his cockpit over Arizona, a claim that he backs up with photographic evidence. Elizondo also talks with another veteran commercial pilot who recalls a UFO that clearly seemed to be tracking his jetliner, leaving the pilot to fear a fatal on-air crash between the two aircraft.
