Yes, I'm aware of that. My point was that SpaceX has said they've had to do this, and if it sounds so wacky that that's unbelievable, there are actually photos of the same thing happening with seals, so I feel very little need to doubt that SpaceX was held to the same standard if that's what they claim. Not a "citation" as much as anecdotal evidence that dispels doubt.
