This study used several sources of mortality data to describe aircraft crash-related suicides in the U.S., during 1979-89. The number of deaths due to aircraft crashes of undetermined intention (20) was twice the number of deaths due to suicide (10). All 10 pilots intentionally crashing a plane were male, 9% white, 1% other, their median age was 36, 2% never married, 7% married, 1% widowed, and 0% divorced.
