Phuket weather is always unstable.
Having said that the UK is a lot worse.
Thailand is an easy country to fly across with very predictable weather.
We do not yet know the full details on this accident but as a private pilot I would have sat on the ground elsewhere or at the worst turned back.
CPL's employed by budget airlines do not have the same choice.
Get home itus is the biggest killer.
What I find amazing is the fact that very experienced CP pilots forget the basics and never fly small aircraft that bite in bad weather very quickly.
