Looked like the fire was from a single point so might have been a pressure relief valve purging after the engine shut down.

Seems to be where the huge port is on the side.

I don't know, I wouldn't think a blowoff valve would pulse like that

They're still there, pressing props. Sounds like the flame vent might be nominal abort mode.

I will honestly be SHOCKED if this is true, but the people on NSF are talking about them trying again tonight. Given that the hopper is/was still venting and nobody has approached the pad yet as far as we have seen... Wow.

Big flare, that usually means they fire Raptor in about 15 minutes.

Wait, that was with fairing. 20m height I bet, or less.

Hold at 2 minutes...

Lotta vapors around the base... This is my first chance to watch one of these...

E go for test! 90 seconds Bob

*burp*

They should have saved the Dragon name for this beast, with all that fire belching. Test aborted after about 3.4 seconds of firing...

Did you watch the first stream by accident? That sounds exactly like what happened one hour ago. They are going for a second attempt right now but no official stream yet.

Maybe. I clicked on the stream a page back and had no way of knowing it wasn't live.... doh. ya whoop, my bad. I'll go sit in the box and feel shame...

Okay, found the EA stream. That looks better, if a little dark... *whistles innocently*

According to Tim Dodd the drone is heading back, away from the hopper... :(

Maybe landed drone to swap batteries since they know they have some time.

Just under an hour left in the test window, some of that probably has to be detanking, so I would say at least 30 minutes usable?

Testing a possible Starship windward side ceramic tile. Maximizing emissivity is best for conductive/particle heating. Nice thing about steel is that tiles can be very thin, unlike carbon fiber or aluminum airframe.

Steel ships are from pre-aluminium epoch, i.e. pre-aviation, i.e. from steel+coal steampunk times.

A rocket engineer in XIX/early-XX is reading this article letter telegraph message:

***

"Well, this fancy aluminium expectedly appears to be a waste of money, compared to the good old steel. As I told them.

Carbon fiber? "Carbon" means "coal". Do they gather fibers of coal dust? Probably. But weave a ship hull of such fibers? What a strange idea. The coal is fuel, they should burn it in the rocket, not make it from.
Though, anyway  it appears to be same bad as aluminium. Who could imagine that a blanket of coal dust is a worse material than steel?..

But the ceramic tiles on top of the rocket look ingenious, I like it.
So, they cover the rocket with fired clay tiles, just like a house roof, to protect it from wind, and probably rain. Also it should protect from headwind when the rocket runs fast.

Maybe even they just buy up potsherds from the junkers on the city market, instead of good tiles.
This costs almost nothing and anyway most of these tiles will shower down from the rocket in flight. I'll try this way first.
(TODO: equip the ground team with helmets to protect their heads from falling tiles.)

We should think up a better name than BFRship. What animal breaths fire and flys but can also beat a dragon in a fight? 

Hmmmm.
