Interjecting with a personal experience (read or don't - is all good):

The curvature of the Earth can be seen from an airplane at certain points and in certain conditions. The first and most memorable time I noticed it was on a flight that passed through (over?) the Arctic Circle. The sun was just starting to come up and it was very easy to see.

 

(A pilot may be better able to explain this, of course.)
