Crashed drone interrupts match at US Open

A crashed drone interrupted a second-round match between Flavia Pennetta and Monica Niculescu at the US Open on Thursday.

The United States Tennis Association (USTA) confirmed the drone, flying from the east, flew into Louis Armstrong Stadium during Pennetta's win.

The drone appeared to be about the size of a pizza box, the type widely available for purchase by everyday consumers.

No spectators were in the immediate area of the crash and there were no injuries.

The NYPD responded and is conducting an ongoing investigation.

Pennetta went on to win 6-1 6-4 to reach the third round.
