RIVERSIDE — There was something wrong with the Cessna 310 when the San Jose pilot first tried starting it.
There was side-to-side shaking when it finally climbed into the air from Riverside airport Monday afternoon.
There was smoke reportedly trailing from the twin-engine plane before it crashed into a house, less than a mile from where it had taken off.
And now, with three people dead, one passenger badly burned and another hospitalized after a dramatic escape from the wreckage, investigators will try to solve the mystery of what really happened — mechanical trouble, human error, difficult conditions or some combination of all those.
The tragedy has hit San Jose hard: Returning home after a cheerleading competition at Disney’s California Adventure Park, two of the contestants’ mothers — Stacey Pierce and Silvia Farelas — were aboard the plane piloted by Pierce’s dad, retired tech veteran Nouri Hijazi. He, along with his wife, Dana, perished when the plane crashed into a home. Farelas, who crawled to safety, lost her oldest daughter, Adine. And though the young cheerleaders were spared, having taken a bus back home, Pierce was badly burned and has been hospitalized in Southern California.
