Use of hydrogen instead of helium

Helium Helium (from el, ἥλιος, helios, lit=sun) is a chemical element with the symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. ...
was initially selected for the lifting gas because it was the safest to use in airships, as it is not flammable.MacGregor, Anne. "The Hindenburg Disaster: Probable Cause" (Documentary film). ''Moondance Films/Discovery Channel,'' Broadcast air date: 2001. One proposed measure to save helium was to make double-gas cells for 14 of the 16 gas cells; an inner hydrogen cell would be protected by an outer cell filled with helium, with vertical ducting to the dorsal area of the envelope to permit separate filling and venting of the inner hydrogen cells. At the time, however, helium was also relatively rare and extremely expensive as the gas was available in industrial quantities only from distillation plants at certain oil fields in the United States.

, by comparison, could be cheaply produced by any industrialized nation and being lighter than helium also provided more lift. Because of its expense and rarity, American rigid airships using helium were forced to conserve the gas at all costs and this hampered their operation. Despite a U.S. ban on the export of helium under the Helium Control Act of 1927, the Germans designed the airship to use the far safer gas in the belief that they could convince the U.S. government to license its export. When the designers learned that the National Munitions Control Board refused to lift the export ban, they were forced to re-engineer ''Hindenburg'' to use flammable hydrogen gas, which was the only alternative lighter-than-air gas that could provide sufficient lift. One of the side benefits of being forced to utilize the flammable yet lighter hydrogen was that more passenger cabins could be added.

After a total of six flights made over a three-week period from the Zeppelin dockyards where the airship had been built, ''Hindenburg'' was ready for its formal public debut with a propaganda flight around Germany (''Die Deutschlandfahrt'') made jointly with the ''Graf Zeppelin'' from March 26 to 29.

''Die Deutschlandfahrt''

Although designed and built for commercial transatlantic passenger, air freight, and mail service, at the behest of the Reich Ministry for Public Enlightenment and Propaganda (''Reichsministerium für Volksaufklärung und Propaganda'' or ''Propagandaministerium''), ''Hindenburg'' was first pressed into use by the Air Ministry (its DLZ co-operator) as a vehicle for the delivery of Nazi propaganda.

was quickly called by Hitler for March 29 to "ask the German people" to both ratify the Rhineland's occupation by the German Army, and to approve a single party list composed exclusively of Nazi candidates to sit in the new Reichstag. The ''Hindenburg'' and the ''Graf Zeppelin'' were designated by the government as a key part of the process. As a public relations ploy, Propaganda Minister Joseph Goebbels demanded that the Zeppelin Company make the two airships available to fly "in tandem" around Germany over the four-day period prior to the voting with a joint departure from Löwenthal on the morning of March 26. While gusty wind conditions that morning would prove to make the process of safely launching the new airship a difficult one, ''Hindenburg''s commander, Captain

As millions of Germans watched from below, the two giants of the sky sailed over Germany for the next four days and three nights, dropping propaganda leaflets, blaring martial music and slogans from large loudspeakers, and broadcasting political speeches from a makeshift radio studio aboard ''Hindenburg''.


First commercial passenger flight

placed on board in the music salon, though the instrument was removed after the first year to save weight. Over the winter of 1936–37, several alterations were made to the airship's structures. The greater lift capacity allowed nine passenger cabins to be added, eight with two beds and one with four, increasing passenger capacity to 70. These windowed cabins were along the starboard side aft of the previously installed accommodations, and it was anticipated for the LZ 130 to also have these cabins. Additionally, the Olympic rings painted on the hull were removed for the 1937 season. ''Hindenburg'' also had an experimental aircraft hook-on

similar to the one on the U.S. Navy Goodyear–Zeppelin built airships ''Akron'' and ''Macon''. This was intended to allow customs officials to be flown out to ''Hindenburg'' to process passengers before landing and to retrieve mail from the ship for early delivery. Experimental hook-ons and takeoffs, piloted by Ernst Udet, were attempted on March 11 and April 27, 1937, but were not very successful, owing to turbulence around the hook-up trapeze. The loss of the ship ended all prospects of further testing.

theories notwithstanding, one hypothesis often put forth involves a combination of gas leakage and atmospheric static conditions. Manually controlled and automatic valves for releasing hydrogen were located partway up one-meter diameter ventilation shafts that ran vertically through the airship. Hydrogen released into a shaft, whether intentionally or because of a stuck valve, mixes with air already in the shaft - potentially in an explosive ratio. Alternatively, a gas cell could have been ruptured by the breaking of a structural tension wire causing a mixing of hydrogen with air. The high

This theory is controversial and has been rejected by other researchers because the outer skin burns too slowly to account for the rapid flame propagation and gaps in the fire correspond with internal gas cell divisions, which would not be visible if the fire had spread across the skin first.
