Helmets and head protection in CF ejections 1967-1973.
During the period 1967-1973, helmet retention and minor head injuries were significant problems in ejections from Canadian Forces (CF) aircraft. There were 73 ejections in which Canadian-designed helmets were worn. Eight-four percent of those who lost their helmets and 38% of those who retained their helmets received minor head injuries. This paper reports on analysis of helmet loss versus air speeed and Q force. Specific problems are addressed, including the fitting and method of wearing helmets, and some guidelines for enhancing helmet retention are recommended.
