Hindenburg’s construction spanned five years, 1931-1936. At Friedrichshafen, Germany, workers stretched fabric, later doped, over its duralumin framework.
Hindenburg’s Hydrogen Cells
When filled, Hindenburg’s sixteen hydrogen cells provided the lift for the lighter-than-air craft. Titanic had sixteen ”watertight” compartments.
