Title Explained: The episode's name is an obvious reference to the ill-fated ship Titanic.
Excelsior is a commonly referenced interjection, for instance famously often used by Stan Lee.
This episode has numerous references to the Hindenburg, a rigid airship which famously and disastrously caught fire. Archer's exclamation, "Oh! The humanity!" is a well-known line from the newsreel of the event, spontaneously given by Herbert Morrison as he watched the ship burn. Being filled with hydrogen, which is highly flammable, the Hindenburg exploded after having caught fire during the landing procedure. The abundant availability of helium in the United States allowed US airships to use that gas instead of hydrogen. This is the case with the Excelsior. To Captain Lammers' exasperation Archer continuously mistakes the properties of helium as being like hydrogen, and referencing the Hindenburg.
When Lana, Malory, Archer and Lammers are discussing accommodations aboard the Skytanic, Lana suggests that she and Malory share quarters and "do the whole Oprah-Gayle thing," referring to the close relationship between Oprah Winfrey and Gayle King.
Captain Lammers also continuously tries, without success, to correct the team's constant reference to the Excelsior as a blimp. Blimps, which are non-rigid airships, are often mistaken for being the same as rigid airships, which is what the Excelsior is.
Waiting for a refill of her drink at the Excelsior's bar, Malory complains the bartender is nowhere to be found: "Guy sees an empty glass, and all of a sudden he's Judge Crater." The reference is to Judge Joseph Crater, who disappeared after visiting a New York restaurant in the 1930s and became known as "The Missingest Man in New York."
Sandu Singh is staying in the "Von Zeppelin suite," where he meets Lana. von Zeppelin was a rigid airship designer and the founder of an airship company called the Zeppelin Airship company. Zeppelin would later become a genericized trademark for similar rigid airships. Archer keeps referring to this room as the "Led Zeppelin suite," a reference to the band, which took its name from a reference to these airships.
When Archer asks Lt. Klauss Kraus where Cyril is, he says to check the "Kaiser Wilhelm suite." Kaiser Wilhelm was the name of twofamous revered German Emperors, or Kaisers. Archer suggests that the company should change the names of these rooms, probably because they refer to famous Germans.
When Lana exclaims "Captain Lammers!" when he reveals himself as the bomber, and Archer says "Nice read, Velma", this is a reference to Scooby-Doo, where Velma (and usually the rest of the Scooby-Doo gang) would very dramatically exclaim the name of the episode's criminal mastermind when he was unmasked.
Archer seems never to have been trained in using the NATO phonetic alphabet or the many other conventions used to prevent misunderstandings on the radio. After Ray chastises him he tries, like many people, to use names. He makes things worse by saying "M as in Mancy," which Gillette is not sure of, then retorts "you of all people..." Ray thinks he said "N as in Nancy" (the term "mancy" is usually directed at an effeminate homosexual).
This episode references the popular comedy Friends, when Cyril walks in on Archer and Lana in a sexually compromising position, and, in the ensuing fight, Lana exclaims, "We're on a break," to which Cyril responds, "fine by me!" This same exchange occurs in Friends, between Ross and Rachel.
The use of 934, 934TX, and 934TXS: The bomb's model number is 934TXS which is confusing when Archer, who does not know the NATO phonetic alphabet, says to Ray it’s “like INXS.”
