They could merely be passing through or performing some training manuvers. Someone told me a few years back that they like to practice and train in this area due to the mountains and the way the air currents flow. I don't know how true that is or if there is any truth to it at all.
A couple of years ago I was at a house up on the top of Red Hill and they were doing some low level training. For whatever their reason,they were dropping flares of some kind as they were fling around overhead. It was quite interesting to watch.
