Query: Interesting Concept

This book is about a space capsule from space that fell down into a small town in Arizona. And the capsule carried an organism from space, that killed the whole population in a small town, except two survivers. Four scientists then meet at an underground site called "Wildlife" and goes on to investigate the microorganism and how the two people managed to survive.At least that is what people in the 60s believed: that bacteria brought down to space by a satellite or organisms from space entering the Earth would cause some kind of crisis like death. But not right now, no, astronauts can come back and go home immediately instead of going through a 3 week decontamination process, since no life form have been found anywhere in space... Yet.This book was written in 1969, and remember that time has changed, and beliefs have changed, so don't read this book and laugh at the idea because 2000's and 1960's are totally different eras.Anyway, it was an intersting book. I liked it!
