So there very well may have been a rupture of the fuel cell. But this is all just back of the napkin stuff and as you say, we'll know when the investigation is done.



I doubt it. The spray from a handheld extinguisher is fairly puny. The fire will entrain much more air on its own. They were definitely too far away at first, but those guys with the extinguishers didn't appear to be wearing proper face masks/SCBA, and it must have been crazy hot getting towards that fire. So I can't blame them for starting further back and working their way closer. Major props to the medical car guys for getting right in there and helping Grosjean over the fence.

Yes and Thanks!!

We are all worse than Armchair Quarterbacks. We're Armchair Accident Investigators. Has there ever been a more ridiculous thing to be?

Let's wait for the investigation before announcing a conclusion.
