What does BMW's blue sky and white clouds mean?

[VonLiam]

That is the logo of BMW, representing the constantly rotating propeller between the blue sky and white clouds. Here is the relevant introduction: Origin: In 1929, BMW produced a new aircraft engine, and on the cover of a magazine published at the same time, the blue and white internal pattern of the BMW logo was compared to the rapidly rotating propeller at the front of an airplane, fully demonstrating BMW's great achievements in aircraft engines. However, this also marked the beginning of the public's misunderstanding of the meaning of the BMW logo. Misunderstanding: Nevertheless, since this perception could boost BMW's car sales—after all, for people, if a car company could handle aircraft engines, making cars could only be described as "using a sledgehammer to crack a nut," indirectly elevating BMW's status in the automotive industry—BMW did not deliberately correct this misconception among the public. Instead, not only did they allow the media to spread this advertisement widely, but they also heavily promoted it in their own publication "Flugmotoren-Nachrichten" (Aircraft Engine News) in 1942. From then on, BMW's blue sky and white clouds became deeply ingrained in people's minds.
