After inspecting the data from the SN11 flight, Elon stated there was a small CH4 (methane) leak that caused a fire on one of the raptor engines which ultimately caused the avionics system to fail. This is what caused SN11 to RUD in midair

The Death Of Density
I don’t think the cities will ever be the same.
Virtue Signaling
…replaces baseball as the national pastime.
What we need is a coalition of the unwoke.

I hadn’t been aware that Neill Ferguson had married Ayaan Hirsi Ali, apparently in 2011.

The Evolution Of The Lineages Of Modernity
A long, but interesting book review, from Jim Bennett.
Senator Ballast
Will he drag NASA down? Jim Meigs is my former editor at Popular Mechanics.

Sorry, link is fixed now.
Too Much Risk Aversion
…is too risky.
Someone should write a book about that.
Spaceship 3
I wonder what the improvements are? They really should have gone with a liquid engine years ago (after the accident in Mojave). They can’t fix the problem with the shuttlecock, but they could fix that.
Continuing To Learn
I’ll look forward to learning what happened to the latest flight attempt.
Is there an SN12? Or will the next test be of SN15?
The Dream Of The 90s
I remember when Nancy moved up there. She told us she was planning it at a Halloween party in 2003 at the late Cathy Seipp’s place.
Europe’s Response To The SpaceX Challenge
…is about as pathetic as one would expect.
I told Clay Mowry back in (I think) 2014 that Ariane 6 would be obsolete before it first flew. He didn’t buy it then, but now he’s with Blue Origin.
