Heres another illustration of perspective and distance...
This one is called Plane Morpher because as it twists and turns through
the sky it seems to take the shape of anairplane at times.
Jeff Filmed this one at out the window at work one afternoon!
You can see just how far I had to zoom into the sky to get that footage,
this UFO would otherwise go unseen by people on the ground.
