Perspective. If they are a 100 times closer then you think they are, they need to move at a 100 times lower speed to cover the same distance. So in stead of 2km per second, they would need to cover 20m per second: that is 72km/h, same speed of a airship.
In 1936 the Zeppelin could travel at a speed up to 135km/h, and that thing was 800 foot long. For a modern hybrid airship, I assume they can get closer to the 200km/h mark.
How are balloons able to move at several kms per second?

The ISS moves 7,2km/s
By your logic it would have to move 252 km/h
No balloon can travel that fast.
Thats about how fast the upper jetstreams move.

You would think that an 800 foot long zeppelin would be visible. Why isn't it?
