Rare colour footage of the Graf Zeppelin II over Friedrichshafen in 1938, filmed by Goodyear Engineer Harold G. Dick. From the documentary "Hindenburg Disaster: Probable Cause." The documentary mistook this footage as color footage of the Hindenburg. This is the only known colour footage of a Zeppelin; the colour footage of the Hindenburg in various video sharing sites was hand-colourized in the 1960s.
