Disclaimer: I am not saying the airliner video is real or fake, only that the video reminded of something Valentich said before he disappeared.
Frederick Valentich (/ˈvæləntɪtʃ/) was an Australian pilot who disappeared while on a 125-nautical-mile (232 km) training flight in a Cessna 182L light aircraft, registered VH-DSJ, over Bass Strait. On the evening of Saturday 21 October 1978, twenty-year-old Valentich informed Melbourne air traffic control that he was being accompanied by an aircraft about 1,000 feet (300 m) above him and that his engine had begun running roughly, before finally reporting: “It’s not an aircraft.”
Valentich: Is there any known traffic below five thousand [feet]?
Robey: No known traffic.
V: I am—seems [to] be a large aircraft below five thousand.
R: What type of aircraft is it?
V: I cannot affirm. It is [sic] four bright, it seems to me like landing lights. . . . The aircraft has just passed over me at least a thousand feet above.
R: Roger, and it, it is a large aircraft? Confirm.
V: Er, unknown due to the speed it’s traveling. Is there any Air Force aircraft in the vicinity?
R: No known aircraft in the vicinity.
V: It’s approaching right now from due east towards me. . . . [Silence for 2 seconds.] It seems to me that he’s playing some sort of game. He’s flying over me two, three times, at a time at speeds I could not identify.
R: Roger. What is your actual level?
V: My level is four and a half thousand. Four five zero zero.
R: And confirm you cannot identify the aircraft.
R: Roger. Stand by.
V: It’s not an aircraft. It is—[Silence for 2 seconds.]
R: Can you describe the, er, aircraft?
V: As it’s flying past, it’s a long shape. [Silence for 3 seconds.] [Cannot] identify more than [that it has such speed]. [Silence for 3 seconds.] [It is] before me right now, Melbourne.
R: And how large would the, er, object be?
V: It seems like it’s stationary.1 What I’m doing right now is orbiting, and the thing is just orbiting on top of me also. It’s got a green light and sort of metallic. [Like] it’s all shiny [on] the outside. [Silence for 5 seconds.] It’s just vanished. . . . Would you know what kind of aircraft I’ve got? Is it military aircraft?
R: Confirm the, er, aircraft just vanished.
V: Say again.
R: Is the aircraft still with you?
V: [It’s, ah, nor-] [Silence for 2 seconds.] [Now] approaching from the southwest. . . . The engine is, is rough idling. I’ve got it set at twenty three twenty four, and the thing is—coughing.
R: Roger. What are your intentions?
V: My intentions are, ah, to go to King Island. Ah, Melbourne, that strange aircraft is hovering on top of me again. [Silence for 2 seconds.] It is hovering, and it’s not an aircraft. [Silence for 17 seconds, open microphone, with audible, unidentified staccato noise. End of transcript.]
