As of 2021 Capt. McConnell is still the U.S. Air Force's top jet ace - a triple ace, in fact - with 16 confirmed kills.
The black and white dress June Allyson wears at the 4th of July party was previously worn by Judy Garland in the "Born in a Trunk" sequence of A Star Is Born (1954) where she sings "You Took Advantage of Me".
The McConnells settle in Apple Valley, CA, just outside Victorville in San Bernardino County.
According to June Allyson in her autobiography, she and Alan Ladd had a romance during the shooting, but it remained platonic because they did not want to be unfaithful to their respective husband and wife.
The people of Apple Valley, CA, gave the McConnells a house on August 6, 1953, as depicted in the film. The house was worth $16,000 (over $164,000 in 2021). The land, materials and labor were donated. It is located at 20822 U.S. Hwy 18, but as of 2021 had not been lived in for many years and is in poor condition.
