The description of the November 1967 X-15 crash is harshly written towards the pilot Major Mike Adams, possibly reflecting the language of the NASA official report. Mike Adams did get the X-15 out of the spin before it disintegrated. Perhaps blaming a pilot no longer there was a way for NASA technical staff to minimise the computer malfunction earler in the flight. I felt the author could have stepped away from official style language describing that fatal incident; putting in that Adams did get out of the spin was something though.
Highly informative. Early chapters on getting up to the sound barrier, the X-15 and lifting bodies are very interesting. Masses of data on the Shuttle obviously- but very little on the decisions which led to the fatal flaws in the design- no escape system and boosters and shuttle strapped to the main tank. The issue of the military requiring such a vast machine is mentioned however.
