"The crew of a Boeing 747 aircraft first witness two unidentified objects to their left while flying over Alaska. Moments later, these abruptly rise from below and close in to escort the 747. Then, a much larger disk-shaped object starts trailing them."

JAL1628

Japan Airline 1628

From wikipedia:

"Japan Air Lines Cargo Flight 1628 was a UFO incident that occurred on November 17, 1986, involving a Japanese Boeing 747-200F cargo aircraft. The aircraft was en route from Paris to Narita International Airport, near Tokyo, with a cargo of Beaujolais wine.

On the Reykjavík to Anchorage section of the flight, at 17:11 over eastern Alaska, the crew first witnessed two unidentified objects to their left.

These abruptly rose from below and closed in to escort their aircraft. Each had two rectangular arrays of what appeared to be glowing nozzles or thrusters, though their bodies remained obscured by darkness.

When closest, the aircraft's cabin was lit up and the captain could feel their heat on his face. These two craft departed before a third, much larger disk-shaped object started trailing them.

Anchorage Air Traffic Control requested an oncoming United Airlines flight to confirm the unidentified traffic, but when it and a military craft sighted JAL 1628 at about 17:51, no other craft could be distinguished. The sighting lasted 50 minutes and ended in the vicinity of Denali."
