I know nothing of the NieR storyline/intro so I might be wrong with my assumptions :

In this case, we may just suppose that Airships do not ventures inside Kholusia because they have no reason to do so.
Spoiler ShB 5.0:
If I remember correctly, until we drive Vauthry off Eulmore, the Eulmoran airships were used only to invade Lakeland, Il Mheg, and Amh Araeng. They didn't seem to pay attention to Kholusian surrounding, as Sin Eaters were just scouting the areas to convert people. And the dwarves never caught the attention of Vauthry and his Minions so, we might assume Eulmorans just didn't know

On the other hand, a spacecraft/whatever crashing on Norvrandt would probably cause a huge commotion near the impact zone. Or maybe it crashed on an uninhabited area ?
I don't know
