A tragic accident. The METARS suggest nothing too bad weatherwise, however evidently something was not quite right. This guy tries an approach from what I hear and he quite rightly doesn't like it so goes around - good call. Why then did he try again straight away - maybe press-onitis, maybe he was watching the fuels guages and didn't have the option of holding, maybe he hadn't thought about taking extra fuel before leaving Bangkok or maybe the company pressurised him to take flight plan fuel and no more??. You know the scenario, short flight, weather seems ok, 3% or 5% contingency fuel on a short flight in reality is NOT MUCH, the weather changes unexpectedly, hence he tries again as the options are running out. Maybe the vis wasn't too good but not bad enough for this to happen. We will have to wait and see the outcome. Don't want to put blame soley on him, maybe company has to take some blame.
Again a tragic accident - there but the grace of god go many of us - IF IN DOUBT TAKE MORE FUEL - GIVES YOU OPTIONS.
