5. THE FIRE

6. The passengers and crew had only seconds to react. Some jumped out of the windows, some fell. Since the Hindenburg was still 300 feet (roughly equal to 30 stories) in the air when it caught fire, many of these passengers did not survive the fall. Other passengers got wedged inside the ship by moving furniture and fallen passengers. Other passengers and crew jumped from the ship once it neared the ground. Even others were rescued from the burning bulk after it had hit the ground. Considering the quickness of the catastrophe, it is amazing that only 35 of the 97 men and women on board, plus one member of the ground crew, died in the Hindenburg disaster. Though it was assumed at the time that the fire was caused by a hydrogen gas leak ignited by a spark of static electricity, the cause of the disaster is still controversial .
