*ping* pilots - are there roads in the sky?

[GundaGunda]

I had my little Foretrex GPS on in the plane from Durban to JHB and back.

What interested me when I looked at the tracks was how far the track up and the track down were from each other.

Why is that? Are there lanes up there ?

I have attached the tracks so you can see what I mean.
