    Memories of Days Gone By...
  

*by J***E on Reviewed in the United States on January 25, 2015*

I have read so much since then, but for a easy to digest history of what "we" think we know about US Secret Aircraft I first got this book in 1992 when in High School and although I lost is when I joined the Navy I decided recently to find it and buy it again.  It's still just as good!

    Has it been 17 years already?
  

*by S***W on Reviewed in the United States on October 1, 2010*

This book is now (2010) about 17 years old.  I got it when it first came out. I probably take this book off the shelf once a year or so, looking up one thing or another. Looking back 17 years, it's amazing how little new information has been made public about hypersonic aviation projects and the happenings at Dreamland aka Area 51 aka Groom Lake.This inexpensive little book still probably has the best history of hypersonic aircraft projects and the challenges of hypersonic (mach 3+) flight.  You would thought that by now we would know for sure whether Aurora ever existed.  Sorry, we don't. Since this book was published, scientists have gotten supersonic combustion ram jets to work up to a point, but they haven't really thought of a useful purpose for them.  Also, there appears to be a revival of the concept of an atmospheric skipping military plane.  This concept was first explored by Dr. Eugene Sanger in Germany before World War II.  You can read about it in the Aurora book.
