Given the audience, while I'll maintain a grain of salt, I wouldn't assume it's a joke. To the extent you can tell from a text transcript, Musk seemed dead serious about taking security precautions against .50-cal hardstarts in future.

“We are close to figuring it out. It might have been formation of
solid oxygen in the carbon over-wrap of one of the bottles in the
upper stage tanks. If it was liquid it would have been squeezed out
but under pressure

That brings up the question of how you get solid oxygen from a liquid
was just used to cool a warm tank....

5500 psi is 0.037 GPa, atm pressure is 1 x 10-4 GPa

That just doesn't sound right.

Where's the list for option 2?--
