Early in the 1920s, the four McDonald brothers are performing in a carnival as a stunt flying team, when they are hired by Mercury Airlines in Newark, New Jersey, to fly the national air mail for the US Air Mail Service. One of the brothers, Colin, instantly falls in love with Lucille Stewart, the nurse giving him a physical. After less than a day, he proposes and she accepts. They marry and Colin starts flying for the company along the east coast. Lucille soon becomes irritated by the brothers' extreme dedication to their work, but Colin promises that his efforts will make it possible for them to buy a home. When the youngest McDonald, Keith, crashes his aircraft and dies, Ronald feels guilty over causing his brother's death, since he was the one who taught him to fly. He quits flying and becomes a car salesman instead. When their friend and colleague "Porkie" is fired for flying recklessly over a passenger train, he also becomes a car salesman. The next brother to crash is Tad. Even though he survives, he is unable to fly again. Colin's former girlfriend, Poppy, pays him a visit and tries to win him back, but he stays true to Lucille. Soon afterwards, their first child, a son, is born. Colin has promised to stop flying once he becomes a father, but when he is offered a raise by the company, he still continues to fly. During his first passenger flight, the wings ice over, and Colin crashes and dies. Colin's boss and Tad are the ones who have to break the news to Lucille, who is hosting their housewarming party. She decides to name her son Keith.
In pre-production, director John Farrow gathered research by flying on American Airlines' cargo flights. Principal photography for Blaze of Noon took place at both Paramount Studios and the Paramount Ranch, beginning on November 1, 1946, and ending in early January 1947. Noted Hollywood movie pilot Paul Mantz flew a Pitcairn Mailwing in the film; he also served as the aerial coordinator. The film was able to gain national and international notoriety when Mantz flew his war-surplus North American P-51C Mustang fighter that he named "Blaze of Noon" to a first-place finish in the 1946 Bendix Trophy cross-country air race.
Reception
Although Blaze of Noon could have been dismissed as out-of-date and more 1930s than 1940s fare, Bosley Crowther noted in his favourable review in The New York Times, "... youthful filmgoers who were mere babes in Lindbergh's salad days will probably find this aerial romance an agreeably entertaining thing."
