How do we know the world is round? For most of humanity, we’ll never get the chance to go up on a NASA mission to see Mother Earth from outer space. But if you have a wide enough vista of clear sky, just watch a commercial jet and you’ll actually see that while it maintains a straight, undeviating course, the earth’s curvature actually makes it look as if the jet is turning.
This shot was taken on the Easter weekend this year. The Authorbloglets and their friends were out and about near the sea – and a couple of camera buffs were shooting the coastline and other familiar scenes.
At one stage, I walked over to a nearby bench to change lenses. Unable to resist watching the condensation trail of an airliner high overhead, I happened to notice the contrail beginning to form an arc.
I instantly forgot all about changing my lens to the zoom I had in my camera bag. Instead, I stuck with my normal lens and shot this second image (below) while practically lying on my back.
