Did anyone see the LOC Precision boys on the History Channel? Looks like even the A-Team can have issues. They went to launch a15 Foot - 12.5" dia. fiberglass rocket using what looked like an O engine. The rear closure failed and everything went shooting up through the rocket destroying thousands of dollars worth of instruments in the payload compartment while sitting on the pad. They were able to launch a smaller rocket later on in the show.
