A former director of the Brazilian Civil Aviation Agency has gone on trial in Sao Paulo over the deaths of 199 people in a plane crash six years ago.

Denise Abreu and two TAM Airlines senior employees have been accused of neglecting air transport safety by allowing the jet to land in heavy rain on the recently resurfaced runway.

The Airbus A320 passenger jet overshot the runway at Congonhas airport.

The BBC's Leonardo Rocha has more details of the factors that contributed to the crash.
