VIDEO: Witnesses say the residents of one of the homes set ablaze in the plane crash in Yorba Linda were hosting a Super Bowl party at the time of the fatal wreck. The small plane lifted off from Fullerton Municipal Airport shortly after 1:30 p.m. Sunday. Authorities said the pilot flew the 1981 twin-engine Cessna 414A about 10 miles before he encountered some sort of mid-air issue. That's when the plane crashed into a Yorba Linda neighborhood. Authorities said the aircraft climbed about 700 feet before making a sudden decline down. The Orange County Fire Authority said there were at least two active structure fires at the scene on Canyon Drive near Crestknoll Drive. There was one home that suffered the most fire damage. Witnesses said when they ran outside, they saw that home immediately engulfed in flames. In that home, four people were killed - two men and two women. The man flying the plane also died in the crash.
