A new look at the design of the Hindenburg


In the PBS television broadcast of May 19, 2021, the topic was “Hindenburg: The New Evidence.” The following image is extracted from that broadcast (it is taken from the 6:30 time point).

Please note that all of the following is my personal interpretation of what I saw and heard during my viewing. The thesis of this broadcast is that the Hindenburg disaster was likely caused by a spark which ignited hydrogen gas that was leaking from one of the rearmost hydrogen-filled bags. The entire assembly as shown above was shrouded in an electrically conductive outer skin, an envelope, which provided streamlining and offered a visually attractive appearance, but was deliberately NOT electrically bonded to the frame.

That outer envelope was electrically floating with respect to the inner frame. Hence, the two structures formed a capacitor which became electrically charged as the airship was coming into Lakehurst, NJ. When the capacitor’s voltage got high enough to strike an arc, the disaster ensued.

Remember: leave nothing floating. Seeing that footage from 1937 should convince even the most hardened skeptic about always observing that precaution.
