The F1 circus arrived in the Yeongam paddock to the news that Peter Sauber would be stepping down from the role of team principal to the Sauber team, and that he had promoted CEO Monisha Kaltenborn to replace him.
Sauber stepping down isn't the good news, obviously. The Swiss team owner has done remarkable things in his years in motorsport, and not just within the rarefied confines of Formula One.
But in the F1 paddock, Peter Sauber has made something of a name for himself as a talent-spotter - the list of past Sauber debutantes is a long one, and includes such names as Robert Kubica, Sebastian Vettel, Felipe Massa, and Kimi Raikkonen.
It goes without saying that he will be sorely missed.
The good news comes about in the form of his replacement on the pitwall, the highly respected Kaltenborn. The former CEO has become Formula One's first female team principal.
Kaltenborn has been being groomed for this role for quite some time, and has - in effect - been acting team principal for much of the season. When Peter Sauber is at races, he's been in charge. But when he's absent, Kaltenborn has been the person ably filling his shoes on the pitwall, not least in Suzuka last week.
She has had a one-third stake in the team since earlier this season, but Kaltenborn's preparation for this promotion essentially began in 2000, when she first joined the team as a legal adviser. Kaltenborn has been the legal mind keeping an eye on contracts, and has also served as Sauber's go-between when the demands of negotiating in English proved too much for the Swiss team boss.
All of Formula One's most powerful women have legal backgrounds, and all of them have earned their positions of power through a combination of merit and sheer hard work.
Kaltenborn is the most high profile, and with this new position she joins the elite group of F1's female power elite.
