Large airships were too sensitive to wind gusts and too sluggish to win against aeroplanes. But today, they have a chance to make a spectacular return.

For decades, die-hard fans of airships have had to accept the fact that their beloved airborne vessels had no chance of making their way back to air travel routes. The ever more technologically advanced aeroplanes are more comfortable and practical than these sluggish giants. Yet the situation changed over a year ago when people in Sweden started talking about ‘flight shame’. Along with the heightened fear of global warming, calculations were being made that, for example, a Boeing 747 emits as much carbon dioxide into the air during 24 hours of flight as 250 passenger cars riding uninterruptedly for a year. Although aeroplanes are responsible for only 4% of the CO2 that goes into the atmosphere in the territory of the European Union, ‘flight shame’ became a hit. The Green parties, especially in Germany, started to bang the alarm that in Europe 45% of all flights are operated on routes shorter than 500 kilometres. The first airlines have just embraced this new trend; at the end of 2019, Dutch airline KLM announced that as of March they will replace flight connections from Amsterdam to Brussels with train routes, together with railway operator Thalys. Likewise, Air France – part of the same holding company as KLM – announced a New Year’s resolution that by 2021, the French air carrier will reduce its domestic flights by 15%.

This trend brings with it the unique opportunity for the much more environmentally-friendly passenger airships to make a triumphant comeback. Much like they did 100 years ago, today’s airships move with the help of propeller-type turbines powered by petrol or diesel engines. However, they emit considerably less CO2 than jet engines. On shorter distances, their speed, on average nine times lower than passenger jets, does not make that much of a difference. Especially since an airship
