heavier-than-air

Won't float naturally

Heavier-than-air describes aircraft that fly despite being denser than the atmosphere—planes, helicopters, and drones, as opposed to balloons and blimps that float.

The Wright brothers achieved the first powered heavier-than-air flight in 1903.

The term appears mainly in aviation history and technical contexts.
