“p 13° The extremely bright lights reflected on snow on the Side of the mountains and seemed even brighter. We wondered if they were searching something on the ground surface or to (attract? )lead something. The flight above Alaska territory is generally in the daytime and it is confusing to identify the kind of lights. It cannot be a base for the spaceship. Is it a movie? There was something. Oh, yes, it is the Alaska pipeline. The lights must be a pump station for the pipeline. I got it. We arrived at the sky above the Eielson Air Force Base and Fairbanks. It was a clear night. The lights were extremely bright to eyes that were used to the dark. How bright it was! We were just above the bright city lights and we checked the pale white light behind us. Alas! there was a silhouette of a gigantic spaceship. We must run away quickly! “Anchorage’ Center. This is JL 1628, requesting a change of course to right 45 degrees” It felt like a long time before we received: “ permission. When we checked our rear there was still the ship. following us: “This is JL 1628. Again requesting for change the. course 45 degrees to the right." We had to get away from that —— -— object. “JL 1628. This is the Anchorage Center. We advise you, ; - — continue and take 360 degree turn." “JL 1628, thank you. we will continue 360 degree turn.” | [Personal statement concerning JAL Flight 1628 sighting of unidentified air traffic, Nov. 17, 1986.
