The National Transportation Safety Board has released a preliminary report on a helicopter crash that killed one Federal Aviation Administration employee and critically injured another.
Preliminary reports, however, don't speculate on the cause of crashes. It could be months before officials say why the chopper went down in a Jackson neighborhood Sept. 1.
The report says there was communication with an air traffic controller while the pilots practiced maneuvers at a Jackson airport. It doesn't indicate they declared an emergency or told the controller there was a problem.
Charles Farmer, of Wetumpka, Ala., was killed in the accident. Larry Wells, of Crystal Springs, Miss., remains hospitalized. Both men were experienced pilots.
