what happened on the M4 out near Penriff yesterday (17/09)? It is just that I was driving out to Aqua golf and there was, i think, some sort or accident on the road. the M4 was close and traffic was backed up for miles. There was also a helicopter landed in the middle of the road on the other side. I came home via the Great Western, but 4 hours later the traffic was backed up down the on ramp and all the way back to Penrith Panters. Does anyone know what happened?
