Wayne was en route from Milwaukee to California when the he "blacked out." The pilot immediately changed course to Omaha, the nearest major airport, where paramedics met the plane on the airstrip. Wayne is reportedly alert and refusing medical treatment.
This is not Wayne's first medical scare. His private jet made emergency landings on two consecutive days in 2012, and he suffered near-fatal seizures in 2013.
UPDATE 2: TMZ now reports that Wayne's Jet was forced to make a second landing after he suffered another seizure mid-flight. The publication says Wayne was being transported to a nearby hospital after landing in Omaha at 5:30 EST.
