Dortmunder U before the night flight

Dortmund → Köln Flughafen → night flight · tourist mode, culture reset, airport sorting · Wind: windy enough that Montenegro felt like it was calling

Saturday started with the practical part: checked out in Dortmund, backpack discipline restored as much as possible, and then a few tourist hours before the route bent west toward Köln Flughafen. The first stop was not heroic: a chocolate shake under a red umbrella, watching the city rush around itself in that directed-chaos way big German city centres do so well.

Dortmund keeps reminding you what it loves. Yellow and black are everywhere — bars, museums, shop windows, small football signals on almost every corner. BVB clearly lives in the city bloodstream. Respectfully: not really my religion. The more interesting part came when the walk reached the Dortmunder U.

The U is the old Union brewery tower, built in the 1920s and later converted for RUHR.2010 into a cultural and creative centre. From the outside it still has that industrial weight; inside it becomes a vertical stack of art, media, research, education, strange objects, and quiet rooms on several floors. Exactly the kind of place that feels like a different world from city commerce: less shopping pressure, more experiments, machines, projections, memory, and questions.

The strongest exhibition thread was Robotron — the GDR technology combine that carried big dreams of computers and microelectronics, but also the contradictions of a planned economy, embargoes, reverse engineering, bureaucracy, and industrial limits. The funny historical echo is that the same Saxony region is now catching up under the Silicon Saxony label. Failed acceleration in one system; a new tech cluster in another. That hit the nerd nerve.

The building also delivered the fun kind of weird: an immersive 3D projection room with a dynamic interactive story, a black grid room with minimal wire-like objects, large industrial-history imagery, and artifacts that were somewhere between museum, lab, and fever dream. The rooftop / lounge level was the soft landing: city panorama, plants, hifi soundbars you can connect to, and enough calm to sit back, listen, and look over Dortmund instead of being inside its rush.

By the end, the counter said about 17,000 steps. Feet tired, head clearer, wind in the streets, Montenegro feeling closer. Then the day became transit again. The FlixBus did its rare but appreciated trick: on time, clean, and almost empty enough to feel private without actually being private.

Köln Flughafen was the usual quick orientation exercise: board, signs, gate logic, baggage rules, security. The pleasant surprise was that the devices could stay inside the backpack. The less surprising part was me apparently looking like the sort of person who needs the extended edition. Shoes off, body scanner not quite enough, human inspection included. I can be clean as a fresh winter snowflake and still get nervous exactly at that moment.

After that, everything smoothed out. The departures board found Podgorica, the apron darkened into airport blue, and the Wizz Air A321neo was waiting outside with stairs at the door. Takeoff worked as planned shortly after 22:45. One hour and forty-five minutes in the air, then the real adventure could finally begin.
