“"The first airline flew lighter-than-air. It was German, luxurious, and occasionally on fire."”
The first commercial airline was not a fixed-wing operation. It was DELAG (Deutsche Luftschiffahrts-Aktiengesellschaft), founded in 1909 to operate Zeppelin airships. DELAG began scheduled passenger service in 1910, carrying 34,000 passengers before World War I with no fatalities. The airships were enormous: the LZ 127 Graf Zeppelin was 776 feet long, with a dining room, sleeping berths, and a lounge with a baby grand piano. It made the first transatlantic passenger flight in 1928 and the first round-the-world flight in 1929. But the Hindenburg disaster on May 6, 1937, at Lakehurst, New Jersey, killed 36 people and ended the era of passenger airship travel. The first fixed-wing airline was KLM Royal Dutch Airlines, founded in 1919, which still operates today. The first U.S. airline was Varney Air Lines, founded in 1926, which later became part of United Airlines. The airline industry has transformed from novelty to necessity, but the DELAG story reminds us that aviation's commercial history began with lighter-than-air ambition.
The Hindenburg disaster was initially attributed to hydrogen's flammability, but modern research suggests that the aluminum powder-doped fabric skin was chemically reactive and may have been the primary combustion source—a lesson in investigating root causes rather than accepting initial assumptions.
