A radio promotion spoofing aliens hacking into a Florence, Alabama radio station spooked students into believing schools would be attacked. To bring attention to a format change at Star 94.9, Brian Rickman, program director for Shoals Radio Group, said the station on Monday began airing conversations between aliens. "The concept being that they heard our frequency several light years away, they didn't like Justin Bieber and the pop music we were playing and they were going to take over the radio station and adjust the format," Rickman said. A flood of phone messages were awaiting Rickman when he got to work Tuesday, he said, including those from police and superintendents of area school systems. Law enforcement still decided to put extra security on campuses as the aliens announced that they would be taking over the radio station at 9 a.m. today.
