LE BOURGET, France -- Families of the 228 victims who died in the 2009 crash of an Air France jet in the Atlantic are awaiting investigators' final report on what happened.

The French air accident investigation agency BEA is releasing its final report Thursday into the crash of the Airbus A330 jet en route from Rio de Janeiro to Paris.

John Clemens, who lost his brother in the crash, said "we are not afraid of having the truth. We want to have the real explanation of what happened and as well recommendations from the BEA on how to prevent this kind of accident from happening in the future."

A preliminary report released last July described a confused crew getting incoherent speed readings from faulty sensors, but it didn't draw a conclusion on what caused the crash.
