Sky Liner is a 1949 American film noir action crime film directed by William Berke. It was released on the bottom half of double bills.
The film follows a selection of passengers on a long distance overnight flight on a silver Lockheed Constellation with Trans World Airlines, through a series of vignettes looking at the passengers and crew. Characters range from a precocious child star (intended to echo Shirley Temple) to businessmen and criminals.
An FBI man (Richard Travis) and a stewardess (Pamela Blake) solve a spy murder on the crowded airliner after a dead man is found in the lavatory. All passengers are suspects. They discover the victim has been stabbed by a fountain pen containing Curare poison.
Filming started 25 April 1949 at Hal Roach's studios. It was described as "a kind of Grand Hotel of an airliner."
It was made by the same writing-directing-producing team that had done Highway 13.
