I just read one of Wankowicz's books about America in the 50s. George Adamski was a famous athor of the bestsellers about meeting UFO in person. He also met with almost all royals and heads of states around the world...but Wankowicz thinks that Adamski was just the crook. In that times people actually believed that the real civilizations are on Mars and on Venus
n 1957 Adamski received a letter signed "R.E. Straith," alleged representative of the "Cultural Exchange Committee" of the U.S. State Department. The letter said the U.S. Government knew that Adamski had spoken to extraterrestrials in a California desert in 1952, and that a group of highly placed government officials planned on public corroboration of Adamski's story. Adamski was proud of this endorsement and exhibited it to support his claims.
However, in 1985 ufologist James W. Moseley revealed that the letter was a hoax. Moseley said he and his friend Gray Barker had obtained some official State Department letterheads, created the R.E. Straith persona, and then written the letter to Adamski as a prank. According to Moseley, the FBI investigated the case and discovered that the letter was a hoax, but charges were not filed against Moseley or Barker.
