Earthmen on a fabulous, peril-journey into outer space!
Storyline: An expedition is sent from Earth to Altair in the constellation of Aquilae (some 17 light years from Earth) to discover what happened to a colony of settlers on its fourth planet, Altair-4. What they discover is how and why an alien race of geniuses destroyed itself overnight while leaving their technology intact at some point in the distant, distant past.
