"KINOGRAMS NEWSREEL: Lakehurst, New Jersey: The Graf Zeppelin reaches the United States after 93 hours aloft / several views of the zep in the air / flying over New York City / CU Dr. Hugo Eckener." Silent.

This appears to be the LZ 127 Graf Zeppelin arriving at Lakehurst on August 4, 1929, prior to the beginning of it's circumnavigation of the globe, which began and ended at Lakehurst.

LZ 127 Graf Zeppelin (Deutsches Luftschiff Zeppelin #127; Registration: D-LZ 127) was a German-built and -operated, passenger-carrying, hydrogen-filled, rigid airship which operated commercially from 1928 to 1937. It was named after the German pioneer of airships, Ferdinand von Zeppelin, who was a Graf or Count in the German nobility. During its operating life, the airship made 590 flights covering more than a million miles (1.6 million km). It was designed to be operated by a crew of 36 officers and men...

Design and development

Built at the Zeppelin Company works (Luftschiffbau Zeppelin) in Friedrichshafen am Bodensee, Germany, between 1926 and 1928, the design of the LZ-127 was patterned on that of the LZ-126 which the company had delivered as a war reparation to the U.S. Navy at NAS Lakehurst, NJ in October 1924 where it was commissioned as the USS Los Angeles (ZR-3). With that project completed, the Zeppelin company's chairman Dr. Hugo Eckener promptly began a two year campaign of lobbying the German Government for funds and permission to proceed with construction of a new airship for Germany. Construction began in 1926 with the aid of a government grant although the majority of the necessary 2,000,000 Reichsmarks (RM) in funding would eventually be raised by public subscription.[3] The LZ 127 was completed and launched in September 1928.

At 236.6 m (776 ft) and a total gas volume of 105,000 m³ (3,707,550 ft³) of which 75,000 m³ (2,648,585 ft³) was hydrogen carried in 17 "lift gas" cells (Traggaszelle) and 30,000 m³ (1,059,435 ft³) was Blau gas in 12 "power gas" cells (Kraftgaszelle)), the Graf was the largest airship in the world at the time. It was powered by five Maybach VL-2 12-cylinder 550 hp engines that could burn either Blau gas or gasoline.

Although the Graf could achieve a top airspeed of 128 km/h (80 mph, 70 knots) at its maximum thrust of 2,650 horsepower (1,980 kW), its normal operational airspeed was 117 km/h (73 mph, 63 knots) at a thrust of 2,150 horsepower (1,600 kW). Some flights were made using only Blau gas carried in the dozen power gas cells which enabled the airship to cruise for up to 100 hours. Using gasoline alone it was able to cruise for 67 hours, and up to 118 hours using both. The Graf Zeppelin had a total lift capacity of 87,000 kilograms (191,800 lbs) with a usable payload of 15,000 kg (33,000 lbs) on a 10,000 km (6,200 mi) flight.

Gondola layout

The flight deck and operational spaces, common areas, passenger cabins, and public toilet facilities on the Graf Zeppelin were all contained in a single contiguous "gondola" structure built in to the forward third of the airship's ventral surface. The forward operational spaces consisted of the flight deck, a map/navigation room with two large open access hatches to allow the command crew to communicate with the navigators, radio room, galley, and a short passage to the main entrance-exit door space. An ascending ladder located in the map room allowed access to a keel corridor inside the hull. The map room also had two large windows, one on each side, which permitted navigators to shoot the horizon and sky with a sextant.

Behind the operational spaces were the main dining and sitting room with four large windows which connected via a long corridor to ten passenger cabins capable of sleeping 24, a pair of washrooms, and dual toilet facilities.[5] The passenger cabins were set by day with a sofa which converted to two beds, one above the other, at night.[6] The crew's quarters were located inside the hull and were reached by a catwalk. The galley was equipped with a single electric oven with two compartments and hot plates on top for cooking...

At the behest of American newspaper publisher William Randolph Hearst, whose media empire was the major commercial backer of the project with four staffers among the flight's nine passengers, the Graf's "Round-the-World" (Weltrundfahrt 1929) flight in August 1929 officially beg
