A couple of hours after the chequered flag was waved at Interlagos, I was chatting to an FIA official about the amazing outcome of the race we had just witnessed. You couldn't have made it up, we reckoned.
We happened to be standing near the bottom of the exterior stairs that lead from the race control building. And as we talked, we saw a BMW Sauber delegation coming down the stairs, consisting of team manager Beat Zehnder, technical director Willy Rampf, and chief mechanic Urs Kuratle. They didn't look like they were celebrating a double points finish.
It was an utterly transfixing moment, for it could only mean one thing - there was a scrutineering issue with one or both of the cars, perhaps one that could lead to an exclusion. In the light of Lewis Hamilton's unsuccessful quest for fifth place, the potential implications were huge.
