"The point of Military Flight Safety is to preserve both aircrew and aircraft from avoidable accidents so that they remain available for unavoidable war. ."
NO it is not.
Get the definition correct.
Go look in the book.
The purpose of Military Flight Safety is to increase operational effectiveness by preserving the people and aircraft.
ie, anything that does not increase operational effectiveness is counter to the purpose of military flight seafety.
Sometimes it is in the best interest of the service to bring everybody home all the time, and sometimes it is not.
