From the link a couple of posts above:
"In this case, no chocks were placed on the wheels. So, as soon as the pilot started the engine - again without following norms, like waiting for an all-clear signal from the ground engineers - the
wheels of the plane moved forward and the engine sucked in the technician standing ahead."
