From the Accident Information Telex issued today:
HAD COMPLETED FINAL ENGINE RUN AND WAS EXITING THE ENGINE RUN ZONE AT THE TIME OF THE INCIDENT.
Is correct, then any and all discussion about parking brakes and chocks are irrelevant. It may then look like a handling problem when leaving the bay - possibly under own power? Those who state that they have carried out this EGR procedure 'in that very bay' might wish to comment on the procedure for entering and leaving the bay. So I would ask (as an amateur) that those who jump on the old A/B argument to close the valves feeding their mouths (or keyboard fingers if you prefer).
