I extend my belated but sincere condolences to the Stigler Family for their loss. God has granted him much peace and happiness over his many years and he can rest in perpetuity. Indeed, knowing of his life gives one pause to reflect that perhaps that is why he was with us for so long. He was well protected by Him as evidenced by Franz's very long and amazing life.
I never met Franz, but for many years we corresponded and spoke about his experiences and family. He was well known and respected in the aviation fraternity for being most helpful and gracious in assisting us all in our research. He always was happy, laughing a lot and never taking himself too seriously. I believe that acts of kindness and compassion, and seeing the best in people and humanity, are his legacies. Let each one of us draw the lessons from Franz's life.
All the best on your flight to eternity Franz.
