Newsreel footage of the May 6, 1937 Hindenburg disaster, where the zeppelin LZ 129 Hindenburg crashed and burned down, was filmed by several companies.
The film is frequently shown with narration, by WLS (AM) announcer Herbert Morrison, who was narrating a field recording on to an acetate disc, and was present to watch the zeppelin's arrival. Morrison's commentary was recorded by engineer Charles Nehlsen, but not broadcast until the next day on May 7, 1937, one of the first times that recordings of a news event were ever broadcast. In 2002, the audio recording was selected for preservation into the Library of Congress National Recording Registry. It has since been combined with the separately filmed newsreel footage. Most of the original newsreels have their own narration, and many composite edits have been made for documentaries dubbed with Morrison's commentary.
