An ardent, readable history, by British travel writer and biographer Botting (Gerald Durrell, 1999, etc.), traces the rise and fall (or self-immolation) of Zeppelin travel.

For nearly 40 years, the Zeppelin vied with the airplane for a niche in the air travel market. The brainchild of the eccentric German Count Ferdinand von Zeppelin, the lighter-than-air vehicles were originally intended as military machines—a use shot down by British airplanes in WWI. After Zeppelin’s death in 1917, management of the project fell to his top assistant, Dr. Hugo Eckener, an experienced and prudent pilot of both the vehicles and the enterprise. The war had proven airplanes faster and more powerful than Zeppelins, but they remained uncomfortable and unable to fly long distances. By contrast, Zeppelins could fly thousands of miles without stopping for fuel, and did so with unmatchable ease and grace. Both advantages made them natural vehicles for transcontinental passenger flights, and it was Eckener’s dream to establish such a service. After struggling to raise funds and develop a clientele, he sought to prove the Zeppelin’s capabilities through a first-class, around-the-world voyage in the largest, most-powerful airship ever built—the Graf Zeppelin. This voyage, the apex of Zeppelin flight, is the focus of Botting’s narrative, which describes the ship as “almost as long as the Titanic, twice as beautiful, and three times as fast”—suggesting that the flight of the Graf Zeppelin is as much Botting’s dream voyage as it was Eckener’s. Reconstructing the flight from passenger accounts, he marvels at what it must have been like to glide along so close to the earth’s surface. The 1928 trip established the Zeppelin as the supreme transcontinental air carrier, a position first challenged by worldwide depression and the rise of the Nazis in Germany, then literally exploded in flames with the Hindenburg disaster in 1937.

It wasn't the airplane that first romanced the public's imagination at the dawn of the twentieth century, but the great airships known as dirigibles, or zeppelins. Championing this great leap into the technological future was a visionary German entrepreneur, Dr. Hugo Eckener.

For Eckener, the development of the airship, especially coming in the aftermath of the First World War, represented an opportunity to shrink the world through safe and speedy international travel. Douglas Botting's engrossing story vividly recaptures the spirit of the times, when new technologies in communication, transportation, manufacturing, and other areas were revolutionizing society. The airship reached its apotheosis with the round-the-world flight of the Graf Zeppelin in 1929. They were a source of wonder wherever they flew, and Eckener was likened to Christopher Columbus, hailed around the world as the great explorer of his day.

I suppose we've all seen the Goodyear or Fuji blimp and wondered what it might be like to go for a ride. (By the way, a blimp is a malformed balloon with rudder and fins, whereas a dirigible or zeppelin has a rigid skeleton making them more suitable for long distance trips and less susceptible to the effects of inclement weather. The U.S. Navy never did much with airships, especially after the Shenandoah was torn apart during a storm over Ohio in 1925.)

Anyway, Dr. Hugo Eckener might be considered the founding father of the modern passenger airship. He's one of those extraordinary people who devote their lives to a particular technology and are singularly good at it. He shepherded the program and was the driving force behind the around-the-world trip in 1929. Eckener was "drafter" by Count Zeppelin to take over his building program after Eckener, then a journalist, wrote critically of zeppelin development in 1906.

Funded by the Hearst fortune, the Graf Zeppelin's voyage was a sensation. That it survived was due to Eckener's skill who had become a meteorological expert and who managed even to tag along on the tails of a typhoon to gain extra speed. Their trip across Siberia was the fastest ever, exceeding even train travel by several days. There were several close shaves. Crossing the final mountain range, they had no reliable charts to indicate the height of the mountains and the maximum altitude of the GZ was about 8,500 feet, but to gain that altitude would have required dumping huge amounts of hydrogen that would have seriously degraded the performance. They wound their way through ever-narrowing valleys between mountain peaks with the sides of the mountains at times only 250 feet away from the GZ. It was an extraordinary display of airshipmanship.

It must have been a terrific way to travel, gliding across the countryside at a height of usually around 1,500 feet, although storms might loosen the sphincter more than a little. Apparently the passenger accommodations were quite luxurious although every precaution was taken to avoid anything that might have contributed to open flame. (It's ironic how many of the passengers got angry because they were not allowed to smoke and immolate themselves.)

As anyone who remembers elementary physics knows, the volume and lifting power of gas is greatly influenced by temperature. In the atmosphere temperature inversions are relatively common and approaching Los Angeles they hit one that had a 10 degree difference. Since in an airship that large, lift increase by 660 lbs for every one degree decrease in temperature, the ten degree difference that day made the ship 4000 lbs lighter which required venting substantial amounts of gas in order to land. That made for an almost catastrophic departure because they had no hydrogen gas at the facility and in order to get off they had to make an aerodynamic liftoff, using the engines to push it into the air. Unfortunately there were power lines at the end of the field. The cleared the gondola by a matter of feet and then had to dive down in order to bring the tail up which had a fin which would have hit the power lines on the way up. Tribute to extraordinary airship piloting but a real horror for the passengers.

Following their return to Germany, Eckener set about creating a transatlantic line and settled on South America as the perfect destination. It was too far for airplanes, and steamships were relatively slower. He inaugurated a trip that was 18,000 miles in length, from Spain to Argentina to Cuba to Lakehurst and back to Europe. There were some bumps along the way. They had to detour around Cuba because of storms and that pissed off some passengers who had paid enormous sums of money for the trip and wanted to land in Cuba. In any case, a terrific storm, had to be crossed in order to reach Lakehurst, something he could not bypass since it was a refueling point. The dirigible was tossed around like a "galloping horse" bucking up and down, terrifying everyone, but the ship suffered almost no damage.

For its brief time, the dirigible filled a need for long distance, nonstop travel. The cost was horribly high for passengers (about $70,000 in today's dollars) for the South America trip) and most of the money was made in first-trip-by-dirigible stamp cancellations and mail. Unfortunately, the dirigible was doomed, for even as the GZ was making its triumphant voyage, a British fighter pilot exceeded 350 mph in his plane. Of course, the Hindenburg was the final nail in the coffin.

Highly recommended.
