SoCal women thankful to survive after plane crashed into their car
Associated Press
FULLERTON, Calif. - A mother and her daughter said Monday they were thankful not to be hurt when a small plane crashed into their car shortly after taking off from an air show.
The plane crashed almost immediately after taking off from the Fullerton Municipal Airport on Saturday, seriously injuring the two men inside. Jay Yoshinaga, 45, of Gardena, and Anthony Albanese, 46, of Brea were listed in critical condition at the UC Irvine Medical Center in Orange, hospital spokeswoman Marcida Dodson said Monday.
The 1986 Bushmaster, a replica 1920s Ford tri-motor plane, crashed seconds after takeoff, just missing the control tower and slammed onto a street, sideswiping Rebecca Perez's Hyundai Elantra. The plane broke apart on impact and erupted in flames.
"There was this real loud bang and air bag going off, crashing noise and ... it stopped my car," Perez, 58, of Buena Park, told KCAL-TV. She was on the way to a doctor's office with her 32-year-old daughter, Valerie Perez.
"We were just baffled and then immediately people came. I was just saying 'Save us Jesus, save us Jesus.' She was like, 'Mom, mom, what happened?' I said 'I don't know, I don't know.'"
Both women were treated for cuts and bruises and released from the hospital.
"It just make everything else, you know, problems and things, so minute," Valerie Perez said.
The crash occurred in front of hundreds of people who were at the small Orange County airport for "Airport Day." The National Transportation and Safety Board was investigating the cause of the crash.
As an air show freak I always hate hearing news like this. I've never been lucky enough to see one but I would hardly call a Ford Trimotor a small plane. I suppose it depends what you compare it with.
