When Dorinda returns home in the plane, she is dressed like Ripley from Aliens, and similarly, she has a ginger tom cat. The cat, however, is named Linda Blair.
The tune Pete Sandich whistles when he's nervous is an Irish jig titled "Garry Owen". This song was the official song of the Seventh Cavalry of the U.S. Army - General Custer's cavalry. When he is nervous, Pete whistles the theme song of a doomed man.
The bomber flown by Pete and Dorinda is the Douglas A-26 Invader, used by the US Army Air Forces in WWII, and the US Air Force in Korea and Vietnam. Al flies the PBY Catalina, a Navy rescue and transport plane in WWII. Dorinda helps Al ferry a Cessna 337 Skymaster, also known as the O-2 when flown by the Air Force in Vietnam. Ted flies a Super Decathalon, an aerobatic airplane.
Although the training base in the movie was supposedly in Colorado, actual filming occurred at the Ephrata, WA Municipal Airport which is a former WWII B-17 training base. Many of the hangars at the airport are original from that era, and evidence of the base is still visible - foundations for buildings, plumbing, the roads and even rock lined walks to the foundations still exist unchanged in the desert. When John Goodman was doused with fire retardant, he was sitting on top of one of a series of earthen bunkers, and walking around the airport you can still see the red retardant stains on the earth. Dorinda's house was a shell built for the movie and sits abandoned at the airport edge. Overall a very interesting place to visit as everything is very well preserved in the desert.
Marg Helgenberger, playing the lovestruck mechanic Rachel, teamed back up with Brad Johnson in 2001 on CBS's CSI. He played Paul Newsome, The District Engineer and new love interest for Helgenberger's character Katherine.
Whilst filming this, Steven Spielberg told John Goodman that he would make the perfect Fred Flintstone. Five years later, Goodman indeed played the famous cartoon character in The Flintstones.
Audrey Hepburn had to be carried on a stretcher by crew members when shooting her scenes in the burned-out forest so that the dirt and ashes wouldn't smudge her white costume. The sweater and slacks Hepburn wears were from her own, personal wardrobe.
Steven Spielberg originally wanted Sean Connery for the role of Hap. Because Connery was unavailable, Spielberg decided to cast Hap as a woman instead and went with Audrey Hepburn.
The Saturday Night Live clip showing on Dorinda's TV features Dan Aykroyd impersonating Julia Child. Dorinda is later briefly seen using "From Julia Child's Kitchen" cookbook.
