Earth is located on one of the outer spiral arms of the Milky Way Galaxy, a band of stars which stretches across the night sky, just one of billions of spiral galaxies in the Universe. It has taken us less than 150 years from the invention of the earliest flying machines to landing on our nearest neighbour. This book is an imaginary idea of 19C flying machines (all of which were actually built, but most of which never left the ground) visiting other planets in our solar system.
