From the essential TVShowsOnDVD.com:
This cleverly written and beautifully drawn series is fondly remembered by many of its original fans and is mostly remembered for "the entirely new patented television cartoon production technique" SYNCHRO-VOX, where real lips speaking the lines would be filmed and then superimposed on the drawings. This technique is still used today, most notably on The Late Show with Conan O'Brien and in the opening credits of Spongebob Squarepants. Nobody who saw Clutch Cargo will ever forget the bizarre juxtaposition of still drawings with real, moving human lips. ...
Clutch Cargo is also famous for its bare-bones animation techniques. Characters are cut off at the waist to simplify animation while they walk, and other motion is simulated by simply agitating the cells. Smoke is blown into the camera lens to simulate explosions. Individual cells are used more than once during a story. But not all details are ignored: Clutch's plane is a rare 1929 Bellanca C-27 Airbus, recognizable by its distinctive wing struts and wheel covers. There are only a few dozen of these planes in existence. Clips from Clutch Cargo appeared in the Quentin Tarantino film Pulp Fiction, and also on an episode of television's Futurama.
