17 YEARS ago, during the processing of one of the most bizarre Freedom of Information Act (FOIA) request experiences I've had, I was told by the FAA they DESTROYED at least 107 pages regarding the UFO encounter with Japanese Airlines flight 1628 (JAL1628). I reconfirmed the documents were destroyed in 2009.
Fast forward to September of 2018 -- I found them tucked away at the National Archives... in fact, I found more than 1,500 pages total, not just 107.
The records are amazing, and include detailed interview transcripts with the pilots, radar data, letters from the public, FAA forms detailing the incident, letters from Philip Klass and Dr. Richard Haines, newspaper clippings, flight path charts, color photos of the simulated radar screens, and so much more!
