Aborted second time -0:48; engines didn't start this time and someone on the live stream called "abort" listened back to the stream "abort abort abort - props con(?) abort" at about 1h:58m in the stream EDIT : announcer did say that engineering stopped it because they hadn't done their review. Maybe the "abort abort abort" wasn't as dramatic as it sounded "We called manual abort. Better to be paranoid and wrong. Brin…

I believe they call it the "net", not the live stream. What is to us a "live stream" is to them their real life!

They held because they didn't manage to finish the review of the previous abort before the new launch attempt.

Can anyone explain what happened?

At T+0, the flight computer ignites the engines, but the vehicle doesn't liftoff yet. Instead, it is held down for two seconds while the flight computer verifies that all engines are working correctly (to prevent blowing up both the vehicle and everything in its surroundings). It seems that the checks failed here and the flight computer aborted launch at T+00:01.

  if enginesOperational {
          // TODO(rocketman): Remove this before the actual launch
          panic("bail out for testing")
  }

10 mins before trying to launch again, Elon tweeted:

   "Increasing helium spin start pressure. Probably
So it was unlikely they would go when they restarted the countdown.
