What do you mean? How high up in altitude, or how high in elevation above the horizon?
It is too clear, and so it is hard to see.
If you are referring to the “atmosphere” as “sky”, it’s typically accepted to start at sea level.
Are you sure you’re only reading Straight Dope… :’)
According to Websters; Sky means upper atmosphere. I believe the boundary between the troposphere and stratosphere is about 7-10 miles up. That would be my vote for where the sky starts.
By the way, does the atmosphere doesn’t start at sea-level at elevations above sea-level.
The sky starts about one micron past your corneas.
What I mean by this is that the blue color of the sky is the cummulative effect of all the atmosphere molecules scattering sunlight. That includes the ones near you as well as those higher up.

This should be posted in General Questions.
I would say the sky starts just above your head. It’s all relative. To an ant, I’m towering up into the sky.
I still don’t know what is meant by the original question, but maybe this month-old thread from the SDMB “General Questions” forum can provide some insight.
