I had a close friend who was a diehard ufologist (his word). He even wrote articles for UFO periodicals. He would browbeat me occasionally into reading UFO books. They were mostly hogwash but one of them gave me pause: "The Day After Roswell" by Col. Philip Corso

This was 1997 when UFO stuff was still fringe, but I remember being astonished by Corso's - direct - references to Harold Brown, SecDef under Carter and an eminent nuclear physicist who had been a Pres. of Cal Tech and was a giant in the American Physics community. The claims Corso made in the book about Brown would definitely have been rationale for a defamation lawsuit against him and Simon & Schuster, yet ... Nothing.

Just sayin', those big-time American academic aristocrats don't allow that stuff. Normally.

So, it's worth a read?
