How to keep traces of chloride out of anything when you're sitting on an ocean of salt water was a problem whose…
This is one of the best technical books ever written. My review on amazon: "Rocket books are often page turners. I reviewed Sutton's "Rocket Propulsion Systems" a few years back.

If you have a background in physics or chemistry, rocket science is a perfect level of semi-light reading. There is…
