JACDEC says ATR72-600, not MA60. Although initially one would definitely suspect an MA60 as part the story, since this type has some of the worst safety records in aviation and no western country wants to approve it (except MOL, if he had a chance!)
From Reuters:
"Thai television showed a photograph of the ATR 72 turboprop plane partly submerged in shallow water on a stretch of the Mekong, the tail severed. Another television channel showed what appeared to be several bodies on the bank of the river."
Sad day. Aviation in Asia is expanding at such a fast pace, keeping up with it generates a lot more risky environment, be it pilot training, systems update, and experience.
