According to historian and writer Atul Gawande, the concept of a pre-flight checklist was first introduced by management and engineers at Boeing Corporation following the 1935 crash of a prototype B-17 at Wright Field in Dayton, Ohio, killing both pilots. Investigation found that the pilots had forgotten to disengage a critical wing adjustment mechanism prior to take-off. Life magazine published the resulting lengthy and detailed B-17 checklist in its 24 August 1942 issue.
