Yesterday I heard and saw on UT, RID 9399156, previously long identified, personally and in the Wiki, as Memorial MedFlight West (South Bend), but apparently it is currently being used as IU Life Line Rotor 40/Life Line 4 (Columbus). Both helicopter services are operated by Metro Aviation. I'm curious if Life Line is flying around in a loaner helicopter that is painted for Memorial MedFlight, if Life Line took over the Memorial MedFlight service, or if Memorial MedFlight got a new helicopter and Metro Aviation repurposed/repainted the old helicopter for Life Line to use; or the least exciting scenario, they swapped the radio from one helicopter to the other and didn't change the RID.
