Quote from The Daily Oklahoman, (June 3, 2004 front page):

...In Supulpa, high winds ravaged the wooden framework, walls and roof of a structure being built at Calvary Baptist Church, pastor Scott Gordon said.

"It was just a big kaboom when it came down," he said.

About 30 seconds earlier, Gordon told the builder to get off the structure, he said. "The minute he came out, it fell down."
