Did they start adding flight cams? I remember watching other launches and it was always incredibly garbage cgi.

same policy: they cut the webcast at payload fairing jettison. All the rocketcams are pointed away from the payload, so they aren't a security concern. More likely, they are bowing from pressure from SpaceX and others who are treating live launch footage as free publicity.

Most the work is currently internal e.g. fuel tanks, or at the pad which is harder to view due to it's elevated and fenced off nature. Basically we need drones to get any meaningful pictures now.

That was misleading
I meant to say that spacex have a service tower on the pad, and they build their rockets horizontally, then lift them vertical once they're on the pad. The service tower is for cryogenic liquid, electrical, and data connections. After DM-1 they will have a connection for people at Kennedy.

Sea Dragon would have been ~$300 million per launch, however it would've got ~500 tons to LEO. The economics would only work if you were using it to launch bulk cargo that was insensitive to the extreme vibrations of launch on that massive rocket. It was designed in an era when we figured we'd be building half kilometer across ring space stations out of aluminum sheet metal launched from Earth. Per kg it would have been significantly more expensive than BFR will be.

They used densified LOx at around -215 C, and chilled kerosene at around -7 degrees C (they'd go colder with the kerosene but it starts to gel up)
A big advantage of methane is that if you densify it by chilling it close to its freezing point it nearly equals the density of kerosene yet doesn't thicken and also gives higher Isp. That's one reason why they chose methane as the fuel for Raptor.

it's also easier to make and purify
the only disadvantage is that it requires a lot of hardware to contain, compared to RP-1 which is fine just sitting around in whatever container you can find for it
