Tampa, Fla. ? Billy Mays, the burly, bearded television pitchman whose boisterous hawking of products such as Orange Glo and OxiClean made him a pop-culture icon, has died. He was 50.

Tampa police said Mays’ wife found him unresponsive Sunday morning. A fire rescue crew pronounced him dead at 7:45 a.m. It was not immediately clear how he died. He said he was hit on the head when an airplane he was on made a rough landing Saturday, and his wife, Deborah Mays, told investigators he didn’t feel well before he went to bed about 10 p.m. that night.

There were no signs of a break-in at the home, and investigators do not suspect foul play, said Lt. Brian Dugan of the Tampa Police Department, who wouldn’t answer questions about how Mays’ body was found because of the ongoing investigation. The coroner’s office expects to have an autopsy done by this afternoon.

U.S. Airways confirmed 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 afterward.

“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.”
