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.

You would think that an 800 foot long zeppelin would be visible. Why isn't it?
Thats about how fast the upper jetstreams move.
How high up is the ISS?
Try googling it.
408 km
Do you agree?
