One of the first strategic bombers used successfully and in significant numbers, the German Gotha series of bombers gained notoriety for bombing London during World War I.  The bombers helped usher in a new, more terrifying era of warfare - no longer were civilian populations well behind the lines safe.  Depicted here is Gotha G.V 670/16 piloted by Walter Aschoff during the fall/winter of 1917.
