Suicide has become a public health problem, as the number of deaths from suicide is increasing every year. Suicides in aviation are also important, since, although they are not numerous, they have catastrophic consequences, such as the Germanwings accident. This book is a documentary review of the suicides that have occurred in aviation and the deficiencies of the system that have made it possible for them to occur, and a proposal is presented to help prevent suicidal behavior in aviation pilots.
