1998. a clear day. My father, LT. col in the Israeli airforce with more than 20 years of experience was approaching landing in Tel-Nof airforce base. Around 1500 feet, my father saw a flash of light coming from the fields below.Within seconds, an object that my father describes as a mushroom shaped metallic flying saucer, with yellow lights running through the middle of the craft, ascended rapidly and passed near the F-15 that he was piloting. A distance of around 100-200 feet. It then accelerated and ascended with insane speed, vanishing form my fathers' view. The landing camera, which records when landing gear is down, did NOT record the incident, even though the Gear was down. Another 2 seater F-15 from my father squadron was a few hundred feet away. Also approaching landing, The navigator on board (backsit) was also a witness to the event, but didn't have my father's clear view. I was around 16 when the event took place. He arrived home with the palest face i have ever seen on him. Later that night he told me the story.He was now ready to tell his story to the public.
