Federal investigators say control cables were broken in the NASCAR plane that crashed into two suburban homes in Central Florida earlier this month.
They don't know whether the cables broke before or during the crash, the cause of which is still unknown, according to the National Transportation Safety Board's preliminary report.
The report says witnesses reported seeing smoke trailing from the plane as it sped low over the neighborhood and seeing its wings
"rocking" before it sharply banked and slammed into two homes.
Five people were killed in the July tenth mishap, including NASCAR Aviation pilot Michael Klemm and Doctor Bruce Kennedy, the husband of International Speedway Corporation President Lesa France Kennedy. Investigators still don't know which one was flying the plane.
