SUMMERVILLE - A preliminary report on a Summerville plane crash last month that killed four people says the pilot made meticulous preparations for the flight.
The report from the National Transportation Safety Board says Peter Radding made several practice landings and takeoffs at night in the days before the crash.
Investigators also found e-mails between Radding and the passengers with the weights of items being taken on the plane and discussions about what could be left behind if the cargo was too heavy.
Radding and the passengers were flying from Summerville to the Bahamas for an amateur radio contest.
Authorities say the plane crashed into trees shortly after takeoff Oct. 21. It could take months for federal investigators to determine the cause of the crash.
