Professor Zander, a rocket-engineering engineer known throughout the world, fulfills his dream and creates Noah’s ark—a ship that allows a leap to other little-known planets. The Noah’s Ark joint-stock company includes wealthy aristocrats and bankers willing to pay for the ship’s construction, and on this ship people can hide from looming revolutions and wars. The adventures of the inhabitants of “Noah’s Ark” while exploring the laws of space are described quite convincingly (1933 year!!!). How will this flight end?
