Medicine Hat Police and local RCMP are continuing to look into a possible downed plane. Police say that Prince Albert 911 notified them yesterday that a handheld radio operator heard a plane calling mayday. The plane was reportedly in the Maple Creek area and Medicine Hat was mentioned as a possible emergency landing site. A portion of the Trans-Canada Highway was closed for a time last night. After police learned there were no commercial aircraft involved and no logged private plans being in the area the highway was opened up again. Officials say it’s possible an un-logged private plane could be involved. The public is being asked to keep their eyes open for a downed plane around the outskirts of the city.
