Deepest sympathy to all affected by this tragedy.
I have been through Phuket once, and on the morning of departure it received extremely heavy rainfall. I suspected that the standing water was deep enough to constitute a contaminant. Initially I could get no information from the airport authority and a request to inspect the runway surface was met with resistance - so I refused to depart. By the time that I persuaded them to take me out to the runway, the rain had been stopped for a while and the surface was drying. During this time other aircraft continued to use the runway. My aircraft docs class a 3mm depth of water as contaminated and the landing distance and crosswind limit are then heavily factored.
Let's hope some old lessons have not just been re-learned.
