The terrorist attacks on the World Trade Center complex in New York City and the Pentagon on September 11, 2001 impacted two Battlestar Galactica revival projects directly and indirectly.
The resultant detrimental implications to both morale and logistically were a critical stumbling-block to "Battlestar Galactica (SDS)", the Fox Network-supported continuation series in 2000. The project was aborted soon afterwards.
Ron Moore's Re-imagined Series contains elements which relate more or less directly to September 11 (see Memorial hallway and "Lest We Forget"). Thematically, the reaction to the colonies' destruction mirrors that of the reaction to the attacks. In Battlestar Galactica: The Lowdown Moore and Eick state that the darkness of the destruction of the Colonies was deliberately intended to spark viewer's emotions of the terrorist attacks and the malaise and sensations of doom those events wrought from people.
