Why German Aircraft Had Spirals Painted On Them

Have you ever wondered what are these strange spiral patterns painted on German aircraft?
Well, the main reason for the swirls on the nose cones was to protect the ground crew. During WWII, the advancement of aviation at that time was incredible. This meant that airfields all around the world had to deal with several planes at once. Ground crew were vital to the German war machine, taking several men to get even the smallest fighter plane ready for take-off.
Having multiple engines, or another plane nearby, makes it easier for crews to walk into the moving propellers. To combat this, spiral or swirl markings were painted on the nose cones.
Firstly, the shapes grab one’s attention, allowing the ground crew to determine quickly whether the propellers are moving or not.
Also, on windy days, propellers can move in the wrong direction. The spirals allowed the maintenance to advise the pilot.
There were also some suggestions that the markings were added to scare off and avoid bird strikes, but there’s no data to historical data to support this claim.
