The Pan Am clipper they are shown boarding is a Martin M-130 named the "Philippine Clipper", registration NC14715, built in 1934. It also suffered a horrible fate as did the DC-3 shown in this film. On January 21, 1943 while on flight 1104 from Honolulu to San Francisco, it crashed into a mountain at 2,500 feet near Ukiah, California at night in bad weather. All nine crew and ten passengers were killed.

Though released six weeks after the Hindenburg disaster, which put a stop to all commercial dirigible flights, the film's climax occurs on a German dirigible and it contains stock footage of a zeppelin, probably the Hindenburg.

The DC-3 seen in the film, NC16002, disappeared on a flight from San Juan, Puerto Rico to Miami in 1948, and has been referred to as a possible Bermuda Triangle mystery.

Includes a shot of what appears to be the San Francisco Oakland Bay Bridge under construction as part of the around the world race.

The famous Broadway columnist, What's My Line? (1950) star and possible murder victim Dorothy Kilgallen contributed to the script of this film. It is (very) loosely based on her participation in an around the world air race, as chronicled in Lee Israel's excellent book, "Kilgallen."

The seaplane they flew in from San Francisco Bay across the Pacific was a Martin M-130 four-engine flying boat.

The Pan Am clipper shown taxiing for takeoff, a Martin M-130 named "Hawaii Clipper", registration NC14714 also had a terrible fate. It was lost on July 28, 1938 while on a flight between Guam and Manila. Nine crew and six passengers were lost. A week-long search failed to find any wreckage or survivors.

The second of nine "Torchy Blane" films from Warner Brothers, made from 1937-39.

The $250,000 taken in the robbery would be the equivalent of $4.2M in 2016.
