Vulcan second certification flight took place today - and there was an anomaly with one of the SRBs. Looks like a blow through on the nozzle.
Got away with it, but it will need to be investigated.

Here's another angle from this morning's flight of Vulcan Cert-2 and the anomalous behavior from SRB no. 1's nozzle section. First 1:12 slowed to 60% speed.

Vulcan flight 2 - SRB out capability!
At L+0:37 Vulcan SRB-1 had a mishap. Currently speculation, but it is thought that the nozzle blew off which led to a case crack. The booster maintained course and SRB separation happened successfully. Nominal insertion of the inert payload has been confirmed so this mishap did not determine the outcome of the flight success.
