What is this nonexistent "exotic matter" they keep referring to?
We had a lot of luck on Venus
We always had a ball on Mars
Meeting all the groovy people

We got music in our solar system
Space truckin' 'round the stars
Come on, come on, come on
Let's go space truckin' . . .

The science of mechanics might perhaps suggest a means, namely, a strong spiral spring. If these advantages and requisites are observed, perhaps in time to come some one might know how better to utilize our sketch and cause some addition to be made so as to accomplish that which we can only suggest." The Editor of the Royal Aeronautical Society journal wrote in 1910 that Swedenborg's design was "…the first rational proposal for a flying machine of the aeroplance [heavier-than-air] type…"
