Langewiesche: “His performance was a work of extraordinary concentration, which the public misread as coolness under fire."
This is largely a distinction without a difference, despite the author's protestation. Obviously, when something like this hapens you show coolness under fire by concentrating on a solution to the problem. If you don't show it, you will become seriously distracted and the risk of failure increases dramatically. I haven't read this hastily-written book but have read some of his other writings. He's an experienced and knowledgeable aviator but sometimes seems "intoxicated with the exuberance of his own verbosity". He also spends too much time attacking straw men. This is less of a problem for non-pilot readers I suppose, and those would often be his intended audience.
