Adored by the Network: In the late 1990s and early 2000s, there was good reason that the USA Network was nicknamed "The Wings Network", and ReelzChannel is quickly taking the same title with their airings of the series in 2012.
Fake Nationality: Tony Shalhoub, Lebanese by birth, played Italian cab driver Antonio Scarpacci.
Antonio's cousin Dominic was played by the not even remotely Italian Maurice Godin.
And the woman they fought over was played by Argentine model Fabiana Udenio.
Missing Episode: "There's Always Room for Cello", in which Roy's son comes out of the closet, was the third episode produced but was not broadcast until halfway through the second season. Homosexuality was still something of a taboo topic for a sitcom in 1990, and NBC had reservations about such a relatively new show tackling the issue.
The Other Darrin: In flashbacks, the Hackett parents were played by different actors than the ones who played them in the series proper.
Real-Life Relative: Tim Daly's sister Tyne appeared in an episode, as did the spouses of Daly, Tony Shalhoub, and Amy Yasbeck.
Shared Universe: With Cheers, characters from which appear several times during the show's run.note Cliff and Norm in "The Story of Joe", Frasier and Lilith in "Planes, Trains, and Visiting Cranes", Rebecca in "I Love Brian". Theoretically, this means that Wings should also share its universe with Frasier, though there was never any direct crossover between the two shows. (Frasier Crane's appearance came before the show Frasier had been created, so the crossover would have still been with Cheers). Apparently they did consider having Antonio make an appearance in Frasier, but Tony Shalhoub asked to play a different character.
What Could Have Been: Crystal Bernard's character Helen Chappel was originally of Greek descent and played by Peri Gilpin (better known for playing Roz Doyle in Frasier). Since Bernard had a Southern accent, Helen was rewritten as a transplanted Texan. Also, Joe and Helen were initially envisioned as an already-divorced couple, but NBC nixed this idea.
