A number of people have said that it used to be generally known that it was possible for the pin to be in but the SPH to be unsafe. Was this just a theoretical possibility or something actually experienced? If so, how did it arise? We know that one route to the unsafe Position 2 was by having the crotch strap through the SPH. Were there other practical ways that Position 2 could be achieved? Was the importance of correct strap in emphasised in seat training?
