Wheel of Fire
"The Wheel of Fire" was a one-hour screenplay by Louise R. Kelley and Alan S. Young.
There, Troy meets Starbuck, now a "guardian of the universe." Starbuck assigns Troy to follow Xaviar (and the Cylon craft) to the year 562 B.C.E. of Earth's ancient past to stop the Cylon from altering or damaging history.
The Raider is destroyed during the event, spinning downward in flames to the Earth. The "Wheel of Fire" is an allegory of the famous vision from the Old Testament prophet Ezekiel, who sees wheels of fire turning in the sky.
As "Galactica 1980" was canceled after 10 episodes, this screenplay was never filmed.
