BEFORE THE MODERN jumbo jet and its first class suites, the biggest and grandest thing in luxury air travel was the German Zeppelin Airship.

Of all the massive Zeppelin's constructed, the most famous was the Hindenburg. The Hindenburg was designed to ferry passengers across the Atlantic in serenity, with the dirigible floating smoothly through the clouds.

The Hindenburg was the first of two "Hindenburg" Class airships constructed by the Zeppelin Company. Construction of the airship began in 1931 and was completed in 1936. The Hindenburg, along with its highly successful predecessor, the Graf Zeppelin, made numerous trans-Atlantic crossings in their brief but illustrious careers.

Constructed out of an aluminium alloy called duralumin, the Hindenburg's massive frame work was filled with 7 tons of hydrogen. Hydrogen is much lighter than air, and allows the massive Zeppelin to carry more people in greater levels of luxury.

However, with an ignition source, an oxidizer, and right concentration, hydrogen can also be incredibly flammable.

The Hindenburg entered passenger service in May of 1936 and carrier up 50 passengers in luxury across the Atlantic.

The legend of the Hindenburg's luxurious amenities are well know, but most have not seen them in living color. So take the opportunity to check out these wonderful photos of the Zeppelin's passengers spaces courtesy of airships.net and the German Federal Archive.

Prior to the age of the airliner, Zeppelin airships ruled the skies over the north Atlantic; connecting cities like New York with Western Europe. Zeppelin's fleet of airships included such colossal creations like the Graf Zeppelin and the Hindenburg (seen here) along with the less famous Graf Zeppelin II.

In fact, here's a photo of Business Insider's world headquarters taken from the Graf Zeppelin in 1929.

The Hindenburg's ultimate calling card was its luxury. The airship's luxury accommodations like the dining room — seen here — were located within its fabric hull, while the gondola where the crew commanded the ship was located below.

However, there were windows so passengers could enjoy the beautiful view as they floated over the ocean.

Located near the dining room was the Hindenburg's lounge. It, too, featured lightweight aluminum seats — see here upholstered in brown. During its first year of service in 1936, the lounge even featured a grand piano. However it was removed in 1937 and was not onboard for the final flight.

The wall of the lounge was covered with a large mural depicting the routes taken by famous explorers, ocean liners, and other Zeppelins.

Next to the lounge was a writing room where passengers could spend some time in peace.

Sandwiched in between the lounge and the dining room were the Hindenburg's passenger cabins. They measured 78" X 66" and featured a pair of bunk beds

One deck below the dining room, lounge, cabins, and writing room was the smoking room and bar. This was an odd feature to have for a ship filled with 7 tons of highly combustible hydrogen. But smoking was much more common back then.

Exactly one year after its maiden passenger carrying flight, the Hindenburg was destroyed in a fiery inferno as it attempted to land at Lakehurst, New Jersey. 35 people onboard the airship along with one person on the ground perished in the tragedy. Amazingly, 62 of the 97 onboard survived.
