Exactly what is the relationship between the ILS being OTS and the crew getting significantly slow on final?
The very last slice of cheese preventing the accident was taken away. Now it's the job of the investigators and the national regulatory authorities to figure out why the other slices were holier than Edam. I suggest cultural attitudes and cross cockpit gradient would be a good place to start. Next would be corporate attitude to screw ups. How about reviewing your initial, line and recurrent training instead of sacking those unlucky enough to find the holes in your procedures?
Procedures can't cover everything.
