The aircraft in question appears to be a 1998 Giles G-202, with the registration N18FJ, according to one witness, photographer and air enthusiast Benjamin Granucci.
Granucci identified the pilot that crashed as Andrew Wright. Orange County's Department of Emergency Services confirmed the pilot was killed.
What I saw was the aircraft come in for a dive. As it pulled up, it suddenly crossed the crowd line and spun towards the ground," Granucci tweeted. "We heard a thud but saw no smoke or flames."
Photos captured by Granucci right before the crash show the airplane's tail shearing off.
