It's not anything to worry about. It may have come off a couple of barrels out of the couple of hundred thousand barrels out there, but that frequency and the fact it is not a safety issue means you should not be concerned about it. The great, great majority of us will only read of it and never see it or know anyone it has happened to, sort of the worry of a hubcap falling off our car while we are driving down the road, has it happened to people, yes, will it happen to us, probably not, will it hurt us, no....<><.... :grin:
