Most people likely don't know, but since 2010 there have been thousands of military accidents on American soil, several of which were fatal. These often occur due to very avoidable mistakes, such as inadequate equipment inspections and poor training and supervision of troops. The families of these soldiers understand the risks their sons and daughters take in combat, but needless deaths while training within American borders are particularly tragic.
Despite periodic news cycles on the matter, military training deaths have always, unfortunately, been an inevitable reality of war preparation. Even as the government spends more on new equipment and training, tragedies do occur in this dangerous field. Working to prevent any deaths is obviously a continuing goal of the government, but aircraft crashes don't mean the military is ill-equipped or underprepared.
