e a freed s ——— TRANSLATES eo Ss. Mi mero OF FAA AK REtaYy Meeting the Future by Kenju Terauchi Page l. Once upon a time if a hunter saw a _t.v., how did he describe it to other people? My experience was similar to this. The north of Alaska in mid-November you cannot even see the sun; the darkness continues until the middle of March. Flight JL 1628, B747 jumbo cargo encountered two spaceships and a Mother ship about 50 minutes above Alaska. There was no danger but it created many questions that a human being cannot answer. Page 2. So I am writing that experience down here. In mid-October, I was excited to hear the special flight. This special flight was to import special French wine from Iceland to Anchorage for approximately a 6 hour and 20 minute flight. It is an extremely short flight compared to most flights. It takes about two-thirds normal flight hours. There are only two landings at Kefurabik (sp.?) International Airport. Page 3. This particular flight was planned to stop at Iceland and increase cargo items rather than flying direct from Paris to Anchorage. However, since being wintertime if the condition of the runway was poor, we may have to reduce the cargo, therefore, everyone was paying special attention to the amount of cargo. The temperature of Kefurabik Airport in November is approximately maximum of 3 degrees C. and the lowest was minus 3 degree C. Page 4. Six of us Japan Airline employees arrived at Kefurabik Airport at midnight and three people welcomed us as usual. We headed on to a new hotel. The bed was extremely small. I understood why the down blanket was only 135 centimeters. We stayed only about 17 hours. The weather became good and the runway was not frozen and we left the Kefurabik at 2042. Page 16. Co-employees are married, have children and are young. I am pleased that nothing happened. The ending of this encounter was very well. We worried because we do not know the purpose of the spaceship, but there is no immediate danger. What do you think about our experience? I hope we humans will meet them in the near future and confirm my experience. ~ [Personal statement concerning JAL Flight 1628 sighting of unidentified air traffic, Nov. 17, 1986. Written by Capt.
