Whimsical Science Fiction: The Spectators, Mr. Isni, Fuel Depot 169

This trio of stories uses the vehicle of science fiction to write a romance (The Spectators), an adventure in physics (Mr. Isni), and a sitcom of two marooned pilots on a deserted planet (Fuel Depot 169). There is enough real science in them to satisfy those who know, enough fiction to make it clear that nothing serious is intended, and enough whimsy to be humorous.
