This is the last episode to feature a battle between Colonial Vipers and Cylon Raiders until the final episode of the series.
Along with the two-part story "The Living Legend", this episode was re-edited and used as part of the film Mission Galactica: The Cylon Attack (1979), which was released in cinemas.
The "medical scanner" used on Adama is actually part of a four-channel stereo receiver. "CD4" was a four channel LP record format.
