The "Wings" universe vs our reality

I was curious about a few things, and went poking around on the internet. Here's what I found:

The producer -- The name of the show's first producer was the same as Frasier Crane's fictional producer, and it turns out there was a sad reason for that. The real-life Roz Doyle died of cancer during the run of Wings, so the creators named a character in their new show in her honor. By the way, Peri Gilpin, who played the fictional Roz, had earlier been a leading contender for the role of Helen, but the network didn't think she was quite right for the role.

The airport -- There is a real Tom Nevers Field on Nantucket, but it's not the airport, it's a playground (https://www.nantucket-ma.gov/2469/Tom-Nevers-Fields-Playground). The real airport is Nantucket Memorial, which oddly enough looks a whole lot like the fictional Tom Nevers: https://en.wikipedia.org/wiki/Nantucket_Memorial_Airport

The airplane -- Like Lassie, there were actually several planes used as "the" plane, which presumably explains some of the camera angles (so as not to show the plane-of-the-day's registration number). But the official plane, N121PP, is reportedly still flying to Nantucket, at last report for Cape Air (motto: "We're Your Wings").

Most of the above is from IMDb's Wings Trivia page: https://www.imdb.com/title/tt0098948/trivia/
