The Red Baron flew several different aircraft during his military career. He started off flying a 2-seater. The aircraft he scored most of his victories was the Albatros D-III and he flew several of these. One of them was the first aircraft he painted all red.Later he received one of the first Fokker Dr.1 Triplanes(3 wings). He flew 4 or 5 of these. One was painted with Red nose and tail on a green plane. His latest one was painted all red.
The Red Baron did not use a symbol. Instead he painted his airplane entirely Red so he would stand out with the enemy and with his fellow airmen. However, he did NOT paint all his planes all-Red. His first was an Albatros D-III. Then he flew the Fokker Triplane but not just one. The last one he flew was all RED. The highest scoring ace of Austria-Hungary painted his Albatros all Red just like the Red Baron. But he painted Skulls on his plane. He painted relatively small skulls just behind his cockpit: one on the left, one on the right and one on the top.
