In the Battlestar Galactica book "Armageddon", author Richard Hatch (who played Apollo on the series) related that the ships of light were the creation of the 13th Tribe. This conflicts with the television storyline where the 13th Tribe are Earthlings (Count Iblis even says they traveled to Earth), and even in this series Earthlings didn't have technology that advanced.
The wrecked ship on the red planet was built from pieces scavenged from sets used in Universal Pictures' television movie Brave New World (1980).
A sequence was filmed in which Apollo, Starbuck and Sheba approach three planets before arriving at Count Iblis' crash site. These planets appear to be Jupiter, Venus and Mercury, teasing that the fleet is getting closer to finding Earth. However, this sequence was deleted from this episode. It was used later in the series finale "The Hand of God".
One of the pilots launching to intercept the lights in space is from the Pegasus' Silver Spar Squadron as he is wearing the helmet from that division.
Last episode to feature Lucifer, Count Baltar's henchman.
