Meaning of “Fly Low”

Origin of “Fly Low”
The idiom “fly low” comes from aviation. Literally, when a pilot flies an aircraft close to the ground, it’s harder to detect on radar — often done to avoid enemies or visibility.
During and after World War II, aviation terms began seeping into everyday English. Phrases like “crash and burn,” “take off,” and “on autopilot” became common metaphors for human behavior. In the same way, “fly low” evolved to describe people who stay unnoticed or avoid attention — just like a plane flying beneath the radar.
So, whether you’re dodging social noise or handling things quietly, you’re doing exactly what pilots did: flying low.
