A statement given by Indonesia’s transport minister says, An AirAsia plane which crashed a month ago with 162 passengers on board climbed at an abnormally high rate before plunging downwards and after that vanishing from radar.
“It is not normal to climb like that, its very rare for commercial planes, which regularly climb only 1,000 to 2,000ft per minute,” he said.
He did not say what brought on the plane to climb so quickly.
