At Ezeiza International Airport, Buenos Aires, December 22, 1962, a UFO was sighted about 3.00 am. Tower operators Horacio Alora and Mario Pezzutto were watching an Aerolineas Argentinas plane which was about to take off, and an approaching DC-8 jet operated by Panagra (a division of Pan American Airways).
One of the operators was radioing landing instructions when the jet captain suddenly broke in:
“What’s that thing at the end of the runway?”

[The] DC-8 jet… was forced to abort the landing and fly back up into a holding pattern.
(The UFO Encyclopaedia, Spencer)
An instant later, the same question came from one of the Argentine airliner pilots. Operator Alora turned and saw a large round object, glowing with an intense fiery light, at the head of runway 1-0-2-8. It had evidently descended while he and Pezzutto were watching the two airliners.
Because of the UFOs’ brilliant glow, Alora could not tell whether it had actually touched down or was hovering just above the runway. At the moment he turned, the UFO rose about ten meters, hovering briefly. Then, rapidly accelerating, it took off on a northeast course . Before it disappeared, it was also seen by Operator Pezzutto.

The pilots of the DC-8 were surprised at the lack of response from the airport staff.
Six months before a similar event had occurred at Camba Punta airport in Argentina, witnessed by the airport director Luis Harvey.
