I believ much has been learned about the eye since ansel. It was said that it would be impossible to see certain things from orbit for example...indeed anything manmade.
But, ships could be seen on the ocean, found by their wake.
Other interesting things could be seen and the eye books were rewritten.
One must be vigilante while being in the pointy end of the plane...birds, planes, toy balloons...and everything else one could imagine.
