The Hindenburg disaster occurred on May 6, 1937, as the German passenger airship LZ 129 Hindenburg caught fire and was destroyed during its attempt to dock with its mooring mast at Naval Air Station Lakehurst in Manchester Township, New Jersey, United States. Of the 97 people on board (36 passengers and 61 crewmen), there were 35 fatalities (13 passengers and 22 crewmen). One worker on the ground was also killed, raising the final death toll to 36. The disaster was the subject of spectacular newsreel coverage, photographs, and Herbert Morrison's recorded radio eyewitness reports from the landing field, which were broadcast the next day.[1] A variety of hypotheses have been put forward for both the cause of ignition and the initial fuel for the ensuing fire. The event shattered public confidence in the giant, passenger-carrying rigid airship and marked the abrupt end of the airship era. After opening its 1937 season by completing a single round-trip passage to Rio de Janeiro, Brazil, in late March 1937, the Hindenburg departed from Frankfurt, Germany, on the evening of May 3, 1937, on the first of 10 round trips between Europe and the United States that were scheduled for its second year of commercial service. American Airlines had contracted with the operators of the Hindenburg to shuttle the passengers from Lakehurst to Newark for connections to airplane flights. Except for strong headwinds that slowed its progress, the Atlantic crossing of the Hindenburg was otherwise unremarkable until the airship attempted an early-evening landing at Lakehurst three days later on May 6. Although carrying only half its full capacity of passengers (36 of 70) and crewmen (61, including 21 crewman trainees) for the accident flight, the Hindenburg was fully booked for its return flight. Many of the passengers with tickets to Germany were planning to attend the coronation of King George VI and Queen Elizabeth in London the following week. The airship was hours behind schedule when she passed over Boston on the morning of May 6, and her landing at Lakehurst was expected to be further delayed because of afternoon thunderstorms. Advised of the poor weather conditions at Lakehurst, Captain Max Pruss charted a course over Manhattan Island, causing a public spectacle as people rushed out into the street to catch sight of the airship. After passing over the field at 4:00 p.m., Captain Pruss took passengers on a tour over the seasides of New Jersey while waiting for the weather to clear. After finally being notified at 6:22 p.m. that the storms had passed, Pruss directed the airship back to Lakehurst to make its landing almost half a day late. However, as this would leave much less time than anticipated to service and prepare the airship for its scheduled departure back to Europe, the public was informed that they would not be permitted at the mooring location or be able to visit aboard the Hindenburg during its stay in port. Around 7:00 p.m. local time, at an altitude of 650 feet (200 m), the Hindenburg made its final approach to the Lakehurst Naval Air Station. This was to be a high landing, known as a flying moor, because the airship would drop its landing ropes and mooring cable at a high altitude, and then be winched down to the mooring mast. This type of landing maneuver would reduce the number of ground crewmen, but would require more time. Although the high landing was a common procedure for American airships, the Hindenburg had only performed this maneuver a few times in 1936 while landing in Lakehurst. At 7:09, the airship made a sharp full-speed left turn to the west around the landing field because the ground crew was not ready. At 7:11, it turned back toward the landing field and valved gas. All engines idled ahead and the airship began to slow. Captain Pruss ordered aft engines full astern at 7:14 while at an altitude of 394 ft (120 m), to try to brake the airship. At 7:17, the wind shifted direction from east to southwest, and Captain Pruss ordered a second sharp turn starboard, making an s-shaped flightpath towards the mooring mast. At 7:18, as the final turn progressed, Pruss ordered 300, 300 and 500 kg of water ballast in successive drops because the airship was stern-heavy. The forward gas cells were also valved. As these measures failed to bring the ship in trim, six men (three of whom were killed in the accident) were then sent to the bow to trim the airship. At 7:21, while the Hindenburg was at an altitude of 295 ft (90 m), the mooring lines were dropped from the bow; the starboard line was dropped first, followed by the port line. The port line was overtightened as it was connected to the post of the ground winch. The starboard line had still not been connected. A light rain began to fall as the ground crew grabbed the mooring lines.
