We had four A10 CATOs at the BEMRC launch today. Three were A10-0Ts that were very recently made — H211021 — October 21st of last year. The A10-3T had been sanded down a bit to fit in a very old model, so the label info was gone. All four blew the nozzles out, and the propellant went out the other end. I believe the fellow who was flying the A10-0Ts is going to file MESS reports on them.
