Did they totally shut down all electrical systems that could be an ignition
source, or is it hopeless having oxygen and methane intimately mixed?
Reminds me of the DCX when it blew up after a landing gear failure.

It was sitting at a tilt after landing. Apparently the landing gear has
been a concern. My supposition was that one or more didn't extend or lock
on extension.
My first thought after the explosion was that the landing gear failure
caused a slow methane leak. That seemed to be born out by the extended
hose down of the vehicle by the ground crew.

Yup, blowed up real good! Vid of the post-landing explosion here:

I think we can say with certainty that some quantity of methane ignited.
Apparently under/inside the base of the vehicle. Beyond that, insufficient
data. Scheduled venting or a flight-damage leak? No data.

Oops! Actually in several pieces now.
Maybe Liquid Methane pooling under the vehicle??

And she's down, in one piece. Lit 3 for the final rotation, shut two
down and landed on one. Slight visible bounce visible at touchdown, fwiw.
Congrats to everyone at SpaceX!
