That's when the government comes clean and tells Superman what they did and ask him to get it back. Superman finds the rocket but the two pilots are missing. He has to determine what happened to them. Turns out they've been enslaved on an alien planet for the last 25 years and Superman has to rescue them and get them home. All while escaping the slave traders himself.
