I was watching the SN4 static fire last night after I came in from the observatory, the first test was great and then i went to bed. I wake up this morning and discovered it was destroyed in second test firing last night. Pretty massive fuel and LOX leak ignited which completely destroyed the ship and damaged the tank farm infrastructure, and the test stand. This is likely to set back the program, even though they have SN05 ready, they need to fix the infrastructure and review everything.
