This is the story of Bill Smith, who is a National Transportation Safety Board investigator hired to determine whether human error is the cause of a jet crash! He and his team of investigators are very confused by the words on the cockpit voice recorder by the crew relating to the crash. But at the same time, a theoretical physicist named Dr. Arnold Mayer has a real professional curiosity about the crash, which borders on science fiction. While giving a lecture, he talks about time travel and the possibility of visitors from the future.
