again. you will see the plane go straight down it smashed into a car in a parking lot in santa ana. thankfully, nobody was in that car. trace gallagher in our west coast news hub. what word do we have on what might have caused that crash? >> as you said, shep, planes don't just fall out of sky. this one appeared to. that's baffling aviation experts. it's high performance aircraft. pressurized fly to $30,000 feet at 270 miles per hour. seconds before the crash the pilot did radio that he had an emergency but did not state the emergency. so, engine failure is a possibility. but it's a twin engine plane and the odds of both failing at the same time are extraordinarily low. this plane has a range of 1500 miles. the trip from concord, just east of san francisco to orange county is about 400 miles. so the plane should have had fuel but witnesses say when the plane was turning, the engines were silent. aviation expert mike boyd
