A vintage World War Two fighter plane crashed near the grandstand at the Reno Air Races in Nevada on Friday, killing the elderly pilot of the P-51 Mustang and injuring scores of people, officials said.
There was no immediate word on how many other people may have died in the crash, although a Federal Aviation Administration official said earlier that multiple fatalities and critical injuries were reported.
Video apparently taken from the stands and posted on YouTube showed a plane crashing nose-down at the show north of Reno. Spectators could be heard gasping, "Oh, my God."
The plane appeared in the video to have crashed near the stands, although the site of impact was not completely clear. Some spectators also appeared to have been sitting in front of the stands, not far from where the crash occurred.
