Narrow Escape Corp
Dallas: Well... some of you may have figured out we're not home yet, we're only half way there. Mother's interrupted the course of our journey. She's programmed to do that should certain conditions arise. They have. It seems that she has... intercepted a transmission of unknown origin. She got us up to check it out.
Ripley: A transmission? Out here?
Lambert: What kind of a transmission?
Dallas: Acoustical beacon. It, uh... repeats at intervals of 12 seconds.
Dallas: I don't know.
