"Carl Macrae's Close Calls: Managing Risk and Resilience in Airline Flight Safety is an intimate account of this learning process, broadly framed in relation to the 'High Reliability Organisations' literature. . Macrae's collated insights constitute an important window into what it means to be working at the frontiers of organisational safety. . Through his work, safety scholars and risk managers of all types stand to learn from aviation's battle-hardened practices." (John Downer, LSE Review of Books, blogs.lse.ac.uk, May, 2017)
