    I am a MUFON Field Investigator who is researching a historic case 557676 It is believed they were interviewed by APRO at the time. I would love to add any additional information.

    It was 9/2/1976 and the people were: Martin (Marty) Napoli, Arnold (Arnie) Goldman, and Jeff Brodsky. I have talked to all three and the stories match within expectation from so long ago. It occurred in N.E Ohio (Gates Mills). It was a ship which displayed a light sequence. When Marty (driving) turned off his headlights, the UFO shut down its lights. It then sped away. Marty believes a band camp of St. Joseph’s High School also had a sighting that night. We have a newspaper clipping where they reported it. This is one of those solid cases which deserves to remain well documented.
