Released yesterday, it goes into Sweden's determined brilliant innovative engineering, radical concept of the SAAB System 37. It goes into the software in great detail and if not a submarine, the innovations and 'design uncertainty' is fascinating and an inspiration to us Sub builders too. Its always been one of my favorite aircraft. at the time of the aircrafts navigation system, it matched or surpassed NASA's MIT's developing the small computer to land the Lunar module. The software now in comparison to today is a door stop, and our pocket calculators are more powerful, but in 1969 it was the best in the world. The Saab 37 was and now the blackbird is retired IS the only interceptor to get radar locks on the SR-71.
