Galactica 1980

The series was originally to focus on Commander Xaviar travelling through time to disrupt Earth history, with Captain Troy and Lieutenant Dillon chasing him as they try to restore history. While that concept was dropped, it reportedly inspired producer Donald P. Bellisario to create Quantum Leap (1989).

At the beginning of the series, the Galactica arrives at Earth in the year 1980. It is said by Adama that their voyage has taken 30 years which means that the events of Battaglie nella galassia (1978) took place around 1950 in Earth time. However, at the very end of the original series (in the episode "The Hand of God"), the Galactica receives a television transmission that shows the 1969 Apollo moon landing. Since the fleet's journey to Earth had only started a few months prior, it means that the events of Battaglie nella galassia (1978) must have taken place at least in the late 1960s Earth time. In fact it would be at least in the 1970s since television signals travel at the speed of light and the Galactica was obviously far more than a light year away from Earth at the time they received the transmission.

Several episodes end with the disclaimer: "The United States Air Force stopped investigating UFOs in 1969. After 22 years, they found no evidence of extra-terrestrial visits and no threat to national security." This is due to the series featuring an Air Force division dedicated to looking for UFOs.

Some episodes in syndication carry the title "Battlestar Galactica," instead of Galactica 1980.
