It is sad that the name of William Samuel Henson is largely unknown today. A man of great vision, he petitioned Parliament for permission to set up an airline — with a business model largely based on post — flying to Egypt, India and China. Parliament turned his proposal down on the grounds that it was 1843 and no-one had invented airplanes yet. Henson knew this, obviously, but could see which way technology was evolving and correctly reasoned that just because he didn’t know how to get an airplane off the ground (he had been involved in numerous experiments around powered flight), that didn’t mean that no-one else would. And when they did, there would be a new business to build on aviation technology. So he started thinking about the businesses that would make sense and, since the post had just been invented in the UK, he looked at how that might work in the future.
As it happens, he was right. When the first commercial aviation contract was signed in 1911, it was for the US mail.
