RIP Allan McDonald & your balls of titanium (and colleagues who pursued the truth alongside you)
4 stars
Heck of a book, chock full of more than just the initial Challenger investigation through the eyes of one who worked with the program and testified (over and over) as to the unheeded warnings he and others provided to NASA. Part memoir, part engineering text, part history, and part a story about ethics in the midst of a blame game, I think this is worth a read for those who want to get the gist how far reaching those 73 seconds became to the engineers, NASA, and those around them.
Should be required reading for all engineers and anyone who is in charge of safety at their jobs.
