Answering Buck's query on where he learned his starfighter skills, Gordon says he was doing this before Buck was born. This line was actually Buster Crabbe and Gil Gerard stepping out of character temporarily. This is a reference to when Crabbe played Buck Rogers in the original 1939 series (Gil Gerard was born in 1943).
During the battle as Twiki and Dr. Theopolis are being pursued by a fighter, Twiki says "Curse you Red Baron." A reference to Snoopy from the Peanuts comic strip as the World War I fighter ace going after the Red Baron.
The original Buck Rogers from the 1930s (from Buck Rogers (1939)), Buster Crabbe, made a guest appearance as Brigadier Gordon in this episode (he was most famous for playing the title role in Flash Gordon (1936) and its sequels).
Jack Palance (Kaleel) also appeared in the 1979 Canadian sci-fi film "H.G. Wells' The Shape of Things to Come", a sequel of sorts to the classic 1936 adaptation of Wells' book, released shortly before this episode aired. The film also featured Eddie Benton, who played Stella in "Twiki is Missing."
