How lives change! An elderly relative of mine started his own photography business in Sidcup, south London in the 1960s and at some point, in the following decade, he decided that he had to learn how to fly so he did. He then specialised in 'photography from the air' mostly to do with commercial buildings I believe. If he was still in business today he could use a drone, I presume so much cheaper but I'm sure not as much fun?
