The good news is that the rocket (I always forget to name them) didn't shred in flight! The bad news is that it wasn't recovered successfully. I think that the ejection charge severed the shock cord and the rocket fell from 4000 feet. The streamer was still in the sky for a very long time, and eventually drifted out of sight.
Did we hear a sonic boom? Well, when it was first launched I was so surprised by the high acceleration that I forgot to listen for one. But when I played the video back, I thought I heard it--two muffled "POP's"--but I'm not sure. If what I'm hearing is the sonic boom, it didn't come exactly .3 seconds after ignition, so I don't think the acceleration was quite as high as the simulation on my computer indicated. The quality of the sound is not very good on YouTube videos. What do you think? Do you hear the sonic boom?
Edit: The sound I am hearing is at about 1:32 in the video.

Well I hear two chuff sounds. These to me sound like motor sound effects. But you know... that would be about the right time for a sonic pop.
