Drone drops at US Open

A drone buzzed over the court during a U.S. Open match in Louis Armstrong Stadium on Thursday night and crashed into an empty section of seats.

U.S. Tennis Association spokesman Chris Widmaier said no one was injured and that the New York Police Department was "conducting an ongoing investigation."

The incident occurred during a game which Italian Flavia Pennetta won 6-1, 6-4 over Monica Niculescu of Romania.

Her initial reaction, she said afterward, was that it might have been a bomb.

"A little bit scary, I have to say," Pennetta said.

"With everything going on in the world ... I thought, 'OK, it's over.' That's how things happen," she said.
