Space

I think D would have liked to be an astronaut.
Here we are today at the Space Fact and Fiction exhibition at Dumfries Museum.
I learned quite bit, such as that space begins at 100kms above the surface of the Earth, at the Kármán Line, named after a Hungarian- American engineer and physicist. He was the first person to calculate that the atmosphere at around this altitude becomes too thin to support aeronautical flight. Interesting to think, as Kármán did in his autobiography, that below this line, the atmosphere/air space belongs to the country below it, but above 100kms, space belongs to us all.
