It is stated in the passage that………… .

The Hindenburg was the last in a series of airships designed to carry passengers and cargo over long distances. It could carry fifty passengers in twenty-five luxury cabins with all the comforts of a first class hotel. Cruising at 125 km per hour, it could cross the Atlantic in half the time of the great luxury ocean liners, which it had been built to compete with. But in 1937, the Hindenburg came to an unfortunate end in New Jersey just as it was about to land. In spite of extensive safety precautions, the highly flammable hydrogen with which it was filled burst into flames. Remarkably though, sixty-two of the ninety-seven people on board were able to escape.
