PS. He was awarded the "Pour Le Mérite" or Blue Max, the highest decoration possible in the German Army at the time, the equivalent of the Victoria Cross or the Congressional Medal of Honour. It had arrived in the post on the day that he died and was waiting for him in its box on his desk but he never returned from that last flight so he never even got to see it, let alone wear it.
Somebody altered a previously taken photograph to show him wearing his Blue Max.
