fed ex ground is not like ups, not every hub has the same equipment some scan packages into the system via a automated system, others rely on the loaders to scan each package manualy. When shtf not every package gets scanned before loading. so maybe it just didnt get scanned. as of a year ago all fedex ground employees must submit to a metal detector and or pat down before leaving the location. stealing your rpk would be very very hard. it either got shipped to the wrong city and will be there eventually or it never got scanned in at its last transfer point and is on its way.
