Zarina's flagship was modelled after Montréal's Olympic Stadium and its support tower. The items were inverted for that alien look with view ports added.
The control room set of the Draconia features a large circular wall of red/green indicator lights from the level 1 control center set for The Andromeda Strain (1971).
The "Astral Queen" miniature from Battlestar Galactica (1978) was painted red and re-dressed as the Zad supply ship. The Galatica shuttlecraft exterior facade subsequently appears in the landing bay aboard Zarina's flagship. The miniature would later reappear in Journey to Oasis (1981).
The series' theme song "Suspension" originally had lyrics, but these were only heard in the pilot and as the closing of "Flight of the War Witch".
The enemy spaceship in "Flight of the War Witch" was unfinished when shooting was scheduled to begin, so this was turned upside down to add an alien look to this.
