WWII letter to the parents of a crewman lost in air combat training:

​

"He did not lay down his life upon the field of battle, but his sacrifice is the same. He was preparing himself to defend those liberties and principles which had been taught to him from his early youth and which were a part of his very being. This may be small consolation to you in your bereavement, but you may well be proud both of his life and of his death."
