Watching the NASA Spaceflight video Astra Test Flight (Launch Vehicle 0006) linked below it seems the launch was terminated, but at least on the video there was no audible Earth-shattering kaboom.
Question: Roughly how high does a rocket have to get before the self-destruct becomes inaudible? Before it becomes Invisible (during the day, or night)?
my attempt at transcription:
T+ 00:00:00 1:33:38 T+ 00:00:52 1:34:30 (rocket now inaudible over the noisy ground LOX tank venting) T+ 00:01:36 1:35:14 rocket has cleared the island T+ 00:01:56 1:35:34 approaching nominal downrange trajectory, tracking (330 m/s 13 km), T+ 00:02:02 1:35:40 and at this point we should have also passed max-Q T+ 00:02:31 1:36:09 engine shuts off, rocket immediately starts rapidly rotating/tumbling T+ 00:02:34 1:36:12 vehicle has passed through max-Q T+ 00:02:38 1:36:16 terminate sent(?) T+ 00:02:44 1:36:22 terminate received
cued at final countdown:
