MEXICO CITY (Reuters) -- A cluster of mysterious objects that surrounded a Mexican Air Force plane, alarming the pilots and sparking a UFO scare, could be a weather phenomenon known as ball lightning, a scientist said on Friday.
The pilots grew nervous during a routine drugs surveillance flight in March when their radar detected strange objects flying nearby and an infrared camera showed 11 blobs of light, invisible to the eye, hovering or darting about their plane.
But nuclear science researcher Julio Herrera said the blobs of light may have been nothing more than ball lightning -- glowing spheres that are little understood
Herrera said electrical discharges in ball lightning could have been attracted to the plane as a conductor.
