Wikipedia’s entry on The Hindenburg:
The disaster is well recorded because of an extraordinary amount of newsreel coverage, photographs, and Herbert Morrison’s recorded on-the-scene, eyewitness radio report from the landing field. The number of journalists present came as a response to a heavy publicity over the first transatlantic passenger flight of the year by zeppelin to the US. Morrison’s recording was not broadcast until the next day. Parts of his report were later dubbed onto the newsreel footage, giving a false impression to many modern viewers, more accustomed to live television reporting, that the words and film were recorded together. Morrison’s broadcast remains one of the most famous in history â€” his plaintive words, “Oh, the humanity!” resonate with the impact of the disaster.
