Doh, you are right, but I still don't understand why they are saying "in all likelihood Serbian national Captain Zslatko Glucika, 55—had fallen asleep on his seat", if they know for sure who was sleeping.
I've flown in near radio silence across the Arabian Sea a number of times. Sometimes the HF would be impossible to use, and you would just wait for Chennai VHF coverage.
Anyway, sleeping has nothing to do with this accident, unless he was sleeping during approach.
