"Footfall" harkens back to the Science Fiction of the 1950's, with the President and the U.S. military dealing with godless Communists and equally godless aliens. A moving dot is discovered on astronomical plates and the evidence is clear: it is a spaceship from another galaxy far, far away. Attempts to contact the aliens are unsuccessful but as soon as they arrive at Earth their intentions become clear: they destroy the Soviet space station, the moon base and then every dam and major installation on the planet by raining down asteroids. To add insult to injury, when the aliens begin landing troops in Kansas, they look for all the world like elephants with trunks performing the function of hands. Now it is up to President of the United States David Coffey, Congressman Wesley T. Dawson of California, USAF astronaut Major General Edmund Gillespie and his sister-in-law Jeanette Crichton, the Director fo the Lenin Institute Academician Pavel Aleksandrovich Bondarev, the unemployed minstrel Harry Reddington, the captured alien Harpanet and several dozen other characters to save the Earth from the alien threat.
Larry Niven and Jerry Pournelle have provided a good old-fashioned "pulp" story, where you go along for the ride. My only substantive complaint is that the Snouts, as the aliens are called for obvious reasons, have a convenient Achilles heel (or two) that allows Earth to have a fighting chance against a technologically superior enemy that REALLY controls the high ground. My favorite part is President relying on a group of Science Fiction writers for advice on how to deal with these strange visitors from another planet, which at least avoids the stereotype of the stupid military advisers just wanting to use nukes at the first opportunity. The "science" in "Footfall" is enough to fuel the story without becoming oppressive; the first time I read this novel I remember thinking it was just an excuse to find a story where launching an Orion was a plausible plot device. "Footfall" is not epic science fiction; it is just a fun read that takes us make to those thrilling days of yesteryear when BEM ruled.
