Do you mean circulation as in air-flow? Or circulation as in traffic?

I don't know about German but French speakers will often use circulation for traffic because it's a false friend.

I suspect in this case it's a false friend - ironically one of the major problems blocking the opening of the airport was actually zero (air) circulation.

Several engineering and electronics companies, led by the German giants Siemens and Bosch, struggled to retain control over the complex fire protection system that included 3,000 fire doors, 65,000 sprinklers, thousands of smoke detectors, a labyrinth of smoke evacuation ducts, and the equivalent of 55 miles of cables.

“Our part, the detection of hot air or smoke ... is functioning,” says Thilo Resenhoeft, a Bosch spokesman. “The responsibility for the dysfunction lies with somebody else.” Siemens spokesman Oliver Santen confirms that the company was originally responsible for building the “automated fire protection facility” and “the control unit for fresh-air circulation.” Testing in 2013 “showed the need for reworking part of the system,” he says. Santen declines to attribute responsibility other than to say that Siemens is “responsible for the reconstruction of the fresh-air circulation system.”

(The issue was not fixed until 2019. Quite disappointed, we didn't even get a Murder Horse out of it.)

As in traffic. And yes, I'm French.

Damned, I am démasqué.

“Right on time”

It was originally scheduled to open in 2007

I know. That was the joke. :shrug:

I considered that but given it was being compared to the Bosch chip factory which did open on time felt it would be worth clarifying for those in other regions not familiar with the situation

if you want to create the impression that it was intentional, you can call it a "soft launch"...

Oh, I didn't know that it has finally opened.

Good foresight by Bosch.
