Starship SN8 Didn't Fly

SpaceX thought they might test the Starship SN8 prototype today. At some point in the not too distant future it is slated to fly up to 40,000 ft and attempt a vertical landing on a nearby pad. Today wasn’t the day. The video feed showed a count down stop at approximately T-13 seconds. I could not tell if it was an abort or a glitch in the feed. The count down resumed and ignition was called at T-0 seconds but the 3 Raptor engines never lit. SpaceX called a stand down for the day. I’ll be interested to find out what they learned.
