An unidentified flying object was spotted 300 m above a plane near Jeffreys Bay before it was seen by the pilots zooming towards earth on Monday night, according to the NSRI.
The UFO was spotted around 21:30 on Monday evening.
“A Boeing 737 cargo aircraft captain and co-pilot, flying from Cape Town International Airport to Port Elizabeth, reported seeing a green object increasing in altitude going past the cockpit of their aeroplane, before reaching a height of about 300 m above them, and then returning back towards earth at high speed past the cockpit of the aeroplane,” NSRI spokesperson Craig Lambinon said.
“The sighting was reported to air traffic control at Port Elizabeth Airport who requested NSRI’s assistance to investigate the possibility that an aircraft or craft may be in difficulty.”
Lambinon said the NSRI’s Jeffreys Bay team monitored the matter throughout the night.
“The green object has not been seen since and there are no reports of anyone, or craft or aircraft overdue or missing.”
Lambinon said the incident happened about 10 nautical miles off the Jeffreys Bay shore.
At first it was thought the object was a green parachute flare, but this was ruled out because the flares “cannot reach that height”.
“No further reports of sightings have been received and the incident remains a mystery,” Lambinon said.
Kouga Mayor Elza Van Lingen said she would need more information about the incident before being able to comment.
