Beware the Universal 'Airport Terminal Pack' DVD
If you are interested in obtaining this film on DVD, do not purchase Universal's "Airport Terminal Pack" of all four Airport films because Airport 1975 is presented incorrectly.
Specifically too much anamorphic squeeze was applied to the DVD video such that when it is expanded, the final picture is not wide enough. The result is objects are not as wide as they should be - actors are thin and tall, the 747 looks three-quarter width, and circles are displayed as slightly vertical ovals.
Clearly a mastering error, Universal apparently felt no reason to fix it.
Despite its being a letterboxed rather than anamorphic presentation, if you're interested in obtaining the film on DVD be sure to pick up the GoodTimes DVD release instead.
