For a couple of days now, people on social media have been posting photos and videos of five military helicopters hovering low over Cleveland and the west side.
By zooming in on photos, the helicopters are marked with RCAF (Royal Canadian Air Force) and have the Canadian flag on them.
Many are speculating that the military helicopters could be part of a scene in the Superman movie being filmed in downtown Cleveland, or possibly training exercises over Lake Erie. Also, the Toronto Blue Jays were in town over the weekend playing the Cleveland Guardians, maybe that has something to do with it.
But, for now, it remains a mystery.
