A father and son from the Midwest died when their plane went down near Shaver Lake Saturday night.
Family members say Patrick Clarke, a businessman from Omaha, Nebraska, and his son, Scott Clarke, a doctor from Springfield, Missouri were on their way to Omaha. Scott Clarke is the registered owner of the twin-engine Cessna.
They took off from Salinas, but about an hour into their trip, something went wrong and their plane crashed in the snowy Sierras.
When investigators found the wreckage, the plane was upside down.
"I heard it real high pitched like it was going down, it sputtered a couple times, then I heard a boom, I went inside and told my boss, and called 911," said Brian Seaiff, who heard the crash while taking a break from work in Shaver Lake.
Several customers at a local bar say they too, heard and saw the plane in trouble.
"I heard a loud bang, like two trains hitting each other, and then it was just quiet, and that was it," said Gloria Hay, who lives in Shaver Lake.
The plane went down in the snowy wilderness.
Investigators with the FAA and the NTSB got a look at the wreckage Sunday morning.
"We have just the fuselage, we're still looking for the wings and the tail section, so if anyone here at Shaver lake sees anything that looks like part of an aircraft we ask them to call law enforcement," said Eliott Simpson, and investigator with the NTSB.
He says the Cessna was last recorded at 27,000 feet, then dropped off the radar just before 7:30 Saturday night.
Investigators still don't know what caused the plane to go down.
