Investigators are examining surveillance video of the fatal explosion of a small helicopter at a Southern California airport fuel station.
A National Transportation Safety Board spokesman said Tuesday that fueling records show the pilot, who was from Long Beach, added more than 40 gallons of fuel about 15 minutes before the Sunday night accident in Corona.
The Riverside County coroner's office identified the pilot as 61-year-old James Bechler of Long Beach.
The NTSB review of the video shows that the helicopter was facing toward the station, lifted off, made a 180-degree turn to the right and tilted forward with its tail coming up. A flash and explosion followed.
Authorities say it's possible the rotors clipped the fuel station but the NTSB has not made a conclusion.
The video has not been released.
