Two weeks ago a Turkish Airlines DC-10 crashed in a pine forest north of Paris. It was the world's worst air disaster and also the first major crash involving the new fleet of giant airliners.
While many people question current standards of air safety, crash investigators are beginning to piece together the wreckage -the first stage in a detective process which could go on for many months.
Tonight's documentary, first shown in Horizon, describes how British investigators work; how from over a million scattered pieces they can arrive at the cause, and make recommendations that contribute to air safety. Narrator FRANK GILLARD
