It is void of evidence. I've read this history since it started appearing in the 1950s. No word of Paperclip being concealed under UFOs or Aliens. You have this idea that secrecy necessarily involves "cover stories." It only involves not mentioning a word about the secret topic. (Some cover stories have happened of course. The CORONA spy satellites were launched as "Discoverer" research satellites. But there's a whole lot of secret stuff that goes unknown because it is...wait for it...secret. But nothing involving our favorite fantasies.)
