We landed the morning after the event. They were using 18C to taxi aircraft from 18L to the terminal. There was a hole in the runway which was a few feet long on the right side and just at the normal touchdown point. This was followed by s - shaped skid marks from the right main gear, which extended about 100 feet and these suggest quite a rapid oscillation of the gear or a lump of rubber spinning. Then there was straight skids marks all the way down.
This airline had 2 B757s parked at remote stands and their engine cowelings were left open and it seemed as if engine parts were being scavenged. No vehicles or engineers at the aircraft.
