In German an airship doesn't "fly", it "fährt". One could have reasonably invented new words for 'flying' depending on whether their motion is caused by flapping wings, buoyancy of light gases, rotating propellers, jet engines, or being fired out of a canon's barrel.
This is the thing about language, you can have strong opinions about it but language evolves through use. Historical attempts to stop this sort of natural drift has just resulted in dead languages nobody speaks like Sanskrit and Latin.
