An Indonesian court has ruled that it will proceed with the trial of a pilot charged with deliberately crashing a passenger jet in 2007, killing 21 people.

In his not guilty plea last month Marwoto Komar, a former captain with Garuda Indonesia, said with 22 years' experience as a pilot he would not have deliberately crashed the plane.

Mr Komar is accused of ignoring 15 automated cockpit warnings not to land as he brought the plane in at roughly twice the safe speed, causing the jet to bounce and burst into flames.

Mr Komar faces three counts of negligence and one count of "deliberately" destroying or damaging an aircraft causing death, charges that carry a maximum sentence of life in prison.

The trial will resume on September 15.
