Strange failure - first auto

a few days ago, I was flying my HK450 Pro, doing a few loops and flips, when the motor started to scream. Thinking the pinion had slipped off the shaft, I managed to flip to throttle hold and auto down into long grass without any damage. It turns out the pinion hadn't slipped - the motor shaft had broken off, and the pinion was still there loose, on top of the motor, a Turnigy Typhoon 2218. It seems odd to me that the shaft should break like that.
