Obesity continues to be a public health concern and its impact on aviation community has not been fully evaluated. Toxicological findings in fatally injured aviation accident obese pilots were examined. The Civil Aerospace Medical Institute's (CAMI's) Scientific Information System was used to develop a dataset, entailing fatally injured obese pilots involved in aviation accidents, 1990-2005. A pilot with a body mass index (BMI) of > 30 kg m2 was considered obese.
