The Hindenburg Disaster

What was Hindenburg Disaster

On May 6, 1937, the Hindenburg carrying 61 crew and 36 passengers arrived hours behind schedule at Lakehurst Naval Air Station in New Jersey. Inclement weather forced this delay. Buffeted by winds and rain, the craft hovered in the area by most accounts for about an hour. The presence of lightning storms were recorded. The landing of the Hindenburg with these types of conditions was against regulations. However, by the time the Hindenburg began its landing, the weather was clearing up. The Hindenburg seems to have been traveling at a fairly fast speed for its landing and for some reason, the Captain attempted a high landing, being winched to the ground from a height of about 200 feet. Soon after the mooring lines were set, some eyewitnesses reported a blue glow on top of the Hindenburg followed by a flame towards the tail section of the craft. The flame was almost simultaneously succeeded by an explosion that quickly engulfed the craft causing it to crash into the ground killing 36 people. Spectators watched in horror as passengers and crew were burned alive or jumped to their deaths. As Herb Morrison announced for the radio, "It's burst into flames.... Get out of the way, please, oh my, this is terrible...Oh, the humanity and all the passengers."

The day after this horrible tragedy occurred, the papers started speculating about the cause of the disaster. Up until this incident, the German Zeppelins had been safe and highly successful. Many theories were talked about and investigated: sabotage, mechanical failure, hydrogen explosions, lightning or even the possibility that it was shot from the sky.

Who investigate the Hindenburg Disaster

The Commerce Department and the Navy led the investigations into the Hindenburg disaster. However, the Federal Bureau of Investigation also looked into the matter even though it technically had no jurisdiction. President FDR had asked all governmental agencies to cooperate in the investigation. The FBI files released about the incident through the Freedom of Information Act are available online.

Why Hindenburg Disaster happens

Some people pointed to a possible mechanical failure. Many of the ground crew later interviewed in the investigation indicated that the Hindenburg was coming in too fast. They believed that the airship was thrown into a full reverse to slow the craft. (See p. 43 of Part I of the FBI documents.) The speculation arose that this may have caused a mechanical failure which sparked a fire causing the hydrogen to explode. This theory is supported by the fire at the tail section of the craft but not much else. The Zeppelins had a great track record, and there is little other evidence to support this speculation.

The next theory, and probably the most outlandish, involves the dirigible being shot from the sky. The investigation focused on reports of a pair of tracks found near the back of the airfield in a restricted area. However, there were numerous people on hand to watch the amazing event of the Hindenburg landing so these footprints could have been made by anyone. In fact, the Navy had caught a couple of boys who had sneaked into the airfield from that direction. There were also reports of farmers shooting at other dirigibles because they passed over their farms. Some people even claimed that joy seekers shot down the Hindenburg. (See p. 80 of Part I of the FBI documents.) Most people dismissed these accusations as nonsense, and the formal investigation never substantiated the theory that the Hindenburg was shot from the sky.

The theory that gained the most popularity and became the most widely accepted involved the hydrogen on the Hindenburg. Hydrogen is a highly flammable gas, and most people believed that something caused the hydrogen to spark, thus causing the explosion and fire. In the beginning of the investigation, the idea arose that the drop lines carried static electricity back up to the airship which caused the explosion. However, the chief of the ground crew denied this claim by the fact that the mooring lines were not conductors of static electricity. (See p. 39 of Part I of the FBI documents.) More credible was the idea that the blue arc seen at the tail of the airship just before it burst into flames was lightning and caused the detonation of the hydrogen. This theory was substantiated by the presence of the lightning storms reported in the area.

The hydrogen explosion theory became accepted as the reason for the explosion and led to the end of commercial lighter-than-air flight and the stalling of hydrogen as a reliable fuel. Many people pointed to the flammability of the hydrogen and questioned why helium was not used in the craft. It is interesting to note that a similar event happened to a helium dirigible the year before. So what really caused the end of the Hindenburg?
