If you enjoy reading, and have any interest in intelligent life on other planets, you want to pick-up a copy of the book THE DAY AFTER ROSWELL by Retired Colonel Philip J. Corso.
Even to those like myself who don't doubt the existence of intelligent life beyond our planet, this book is an eye opener.
I'm only to chapter 12 so far, but here's that chapter's title: The Integrated Circuit Chip:From the Roswell Crash Site to Silicon Valley.
In this extraordinary memoir Colonel Corso gives details and names names describing how the US Government found, covered-up and used alien artifacts to change the course of twentieth-century history.
