Your picture of the UFO reminds me of pictures in a book by George Adamski(SP) which were Aliens from Venus. I saw it in my parents bookcase in the 50’s and read it. God there were spacemen from venus, it said so. I ran downstairs to proclaim this message. My Mom gave me this look and said Oh we forgot to throw that away, It’s trash.
Adamski evidently found out some things and started publicizing some things that the PTB did not want unfetteredly released.
They reportedly pressured him to then write and say things which were absurdly untrue in order to trash everything he had said and might say.
