Eyewitness Shelby Lovitt, a senior at University High school, said she heard a loud boom just before noon and then saw a plane go down. She said she also saw someone eject from the plane with a parachute. She ran out into field and saw black smoke and flames.
The school had been put on lockdown and no one is allowed to leave, she said.
Thick, black smoke could be seen rising from an area north of Governor Drive and west of Interstate 805, according to eyewitnesses. That smoke turned white as the firefighting effort began.
