Many people believe in a lunar conspiracy: that the U.S. government filmed the Apollo missions in a movie studio. Conspiracy theorists doubt that NASA had technology advanced enough to send a rocket to the moon, considering that, in those days, simple calculating computers were as big as houses and were very slow. Even today, rocket scientists are unable to fire a rocket and have it land upright. Conspiracy theorists are curious: How can NASA claim to have done just that in the 1960s?
