We need more people like him telling us that from 6 miles above the Earth that people throw visible shadow on all but two days a year.

 
6 miles is 31,680 ft altitude.  That's rather low for earth
satellites.  The minimum orbital altitude is about 104 miles (167.4
km), where air resistance starts to become a problem.

This is free, higher resolution are available if you're willing to pay
for it, and the best resolution is not available to the general public.

Aerial photos and satellite images can be post-processed to remove
shadows using Photoshop or similar photo editing tools:

However, removing shadows is not always beneficial.  The length of a
shadow can be used to estimate the height of a building.
