An unresponsive plane originally set to travel from Rochester, New York, to Naples, Florida, has drifted into Cuban air space, according to NORAD.
Two U.S. F-15 fighter jets trailed the plane to Cuba, before breaking off. A Cuban fighter jet is now trailing the plane, which may be running out of fuel.
This is a developing story, check back for updates.
UPDATE: News reports say the plane crashed off the coast of Jamaica. NBC reports that the plane's two passengers, Larry Glazer, owner of a real-estate development firm, and his wife, Jane, are both dead.
