SELFRIDGE AIR GUARD BASE, Mich. (My TV20 News at 10) --- Wing walker Todd Green's own mistep caused his death.
That's the early word tonight from the National Transportation Safety Administration that has been investigating the August 21st incident in which Green fell 150 feet to his death during an air show.
Green tried to transfer from a plane to a helicopter when something went wrong.
Federal investigators claim in their preliminary report, pilots told them Green left the cockpit too soon.
The report states Green had let go of the airplane, and tried to grab the helicopter skid before it was in place.
It could take a year for the NTSB to complete their investigation and issue their final report.
