Under the occupation, the Germans believed the innocuous book and allowed the publication. But this writing encourages man to prevail over despair. It allows him to live with a heart that exceeds the test. Also this book he gave from the heart to other French crushed in defeat. And he gave the heart to a young German soldier who saw himself swept his (from his testimony after the war in a meeting of St-Exupéry admirers).
"War Pilot" shows that life beyond death and that man has, how it was said, a soul.
