News Changes to the SpaceX BFR rocket.

[GLS]

T-40 seconds, issues: booster tank press (fixed), second stage purge.

 

[GLS]

Issues resolved, count about to resume.

 

[GLS]

T-25 seconds...

 

[GLS]

T0, liftoff!

 

[Urwumpe]

Can it be, that the streams are not synchronized?

 

[GLS]

Several flashes in the engines, but is going up!

 

[GLS]

Several engines visually out.

 

[GLS]

Seems to be quite pitched up due to the loss of thrust, but still going... probably not as well as it needed....
And loss of control...

 

[Urwumpe]

Cartwheeling!

 

[GLS]

Quite a good imitation of the early Atlas rockets, with the tumbling.

 

[GLS]

boom

 

[Urwumpe]

Don't know why they are cheering. I would be terribly disappointed, especially if its such a trivial failure.

 

[GLS]

Maybe 5 or 6 engines shutdown quite early, and that was too much judging by the nose up attitude...

 

[Urwumpe]

Also, why had they still talking like a nominal situation, when it was already in the flip without separation confirmed?

 

[GLS]

Don't know why they are cheering. I would be terribly disappointed, especially if its such a trivial failure.

Yeah, I'd probably feel the same...


A quick review of the video shows that one flash coincides with debris flying off the bottom of the vehicle. Uncontained engine failure, and a N1 scenario? The flame seemed asymmetrical, so there could be a (small) fire inside.

Oh, it really looks like a fire in the middle, and at least 6 engines off.

 

[jarmonik]

That ended up like many flights in KSP, uncontrolled spinning. Sad to see if it was something trivial like a stage separation that doomed the flight.

----------------

 

[Urwumpe]

It lifted off the smoke already with 3 engines out. Also it was rolling slowly on the onboard camera.

 

[Pioneer]

Well, it all got off the ground...
That is somewhat a success...

 

[Urwumpe]

I checked, the roll started when the second big flash appeared. So, loss of control was already way earlier.
