Mays' wife, Deborah Mays, told investigators that her husband had complained he didn't feel well before he went to bed some time after 10 p.m. Saturday night, Tampa police spokeswoman Laura McElroy said.
U.S. Airways confirmed Sunday that Mays was among the passengers on a flight that made a rough landing on Saturday afternoon at Tampa International Airport, leaving debris on the runway after apparently blowing its front tires.
Tampa Bay's Fox television affiliate interviewed Mays after the incident.
"All of a sudden as we hit you know it was just the hardest hit, all the things from the ceiling started dropping," MyFox Tampa Bay quoted him as saying. "It hit me on the head, but I got a hard head."
McElroy said linking Mays' death to the rough landing Saturday afternoon would "purely be speculation." She said Mays' family members didn't report any health issues with the pitchman, but they said he was due to have hip replacement surgery in the coming weeks.
