I'm an avid scuba diver. Ever the domain of the wealthy, scuba diving required both access to the ocean and a shite ton of money for travel & equipment. Not really having any of it, this awesome hobby just kinda passed me by.
WWI: Manfred von Richthofen – the Red Baron, was a German fighter pilot with the Imperial German Army Air Service (Luftstreitkräfte) during World War I. He is considered the top ace of that war, being officially credited with 80 air combat victories.
Quite possibly the greatest hat worn during the Great War .Generalfeldmarschall August von Mackensen, officer in the German Army. Wearing the Totenkopf (skull and cross bones) which was part of German military gear since the century.
