I first read this book when I was in junior high school in 1960. It totally floored me and I wondered why NASA was having so much trouble getting into space.
If you ever get a chance to see the movie take my word for it an give it a pass. When I saw the movie they made in the late 1960's, early 1970's the only thing I recognized was the hero/main character had the memory of the sounds. The movie is complete garbage.
I highly recommend the book and if you have teen age children then let them read it. I think the kids will really enjoy it as I did at that age.
