I have read many of the viewer comments on this film and I can say that most were right on target so there isn't much point in my repeating what they've already said.
My main comment would be: Save yourself the time and expense to see this film and rent "Airplane!" instead. They are essentially the same film with the only real distinction being that "Airplane!" actually was intended to be a comedy.... and a damned good one at that. In fact, as I recall, "Airplane!" was named the best comedy ever made by the American Film Institute. This is quite phenomenal when you consider that it was nothing but a spoof of "Airport 1975". And this may be the one and only truly distinctive aspect of "Airport 1975". That is, it did inspire a truly great film. Otherwise, it had very few redeeming qualities.
The film is nothing but a haphazardly thrown together collection of all the film clichés that could be squeezed into the allotted run time. I recently watched it for the first time since its original release mostly out of sheer curiosity. I remembered it being bad.... as all the sequels to "Airport" were. They were all presumably made as serious films but they were all so sloppily made with such terrible scripts that you couldn't help wonder why they weren't just released as comedies in the first place. For example, as has been well documented in other viewer comments, how could anyone take Linda Blair's and Helen Reddy's roles seriously? I mean, how could they keep straight faces with the scenario and dialogue they were supposed to work with? All that was missing was a laugh track.
I am glad I read some of the IMDb comments as I was viewing "Airport 1975" on AMC because they really added to my enjoyment of the comic aspects of the film.
As I said, this was the first time I had watched it in about 30 years and in the meantime I had of course seen "Airplane!" But until rewatching "Airport 1975" I did not realize the degree to which "Airplane!" was inspired by "Airport 1975". At times, I was dumbstruck at how scene after scene were all spoofs of actual scenes from "Airport 1975". And this made the film very entertaining to me when otherwise I may have just hit the channel button on the remote after the first 10 minutes of so of the drivel that "Airport 1975" actually is.
