Sorry, I don’t have a website with a lot of UFO stuff on it. A minor amount but not about those incidents.
MUFON
CUFOS
and the like
MIGHT have more of that. I’m sure ATS does.
You’ll have to search, though.
My replies come out of all the years of reading since 1962. All mushed together.
I don’t recall whether any airliners totally disappeared, or not. Just that some were downed . . . evidently in fairly quick retaliation for UFO’s being targeted.
