While this applies to 1943 planes, it should also be noted that the exact same mechanisms are responsible for contrails from modern jet aircraft. Jet engines burn fuel that is essentially the same kind of chemical as used by old prop planes. They produce water vapor, and a contrail can result if the weather is right. If the weather aloft is humid, then the contrail can persist for several hours.
