In a remarkable display of cooperation, the U.S. Coast Guard and the Royal Canadian Air Force teamed up to evacuate two critically ill passengers from a Carnival cruise ship. One passenger suffered sudden cardiac arrest and another faced a life-threatening esophageal blockage near Cape Flattery, on the U.S.-Canada border.

The U.S. Coast Guard has issued an alert after a live military flare washed up on Chicago’s Montrose Beach. With three similar devices still unaccounted for, authorities are cautioning the public about potential dangers along the Lake Michigan shoreline.
