"Mass casualties" were reported at a Reno, Nevada air show after a plane crashed Friday into the box seat area near a grandstand at the National Championship Air Races and Air Show.

The pilot, Jimmy Leeward, from Ocala, Florida, was likely killed in the crash. He was flying a P-51 Mustang.

At least three people died and more than 50 people were transported from the scene with injuries, officials said shortly after the crash Friday at the National Championship Air Races and Air Show.

But there could be "mass casualties," officials said.

According to one local hospital, Renown Medical Center, they received 27 patients, 12 who were in critical condition. It reported that two patients -- a male and a female -- died.

This video from the scene, posted on YouTube, showed a plane plummeting from the sky, sending up clouds of dust and debris.
