Muddergoose,
After you ream others for their posts you then go on to criticise the pilot. Nice one.
And BTW 230nm in a high performance turbo prop is not far, a time interval of probably under an hour. Nothing for a professional pilot, and given the wheels and flaps were down I doubt he was asleep.
He did have lots of experience and had an experienced pilot next to him in the form of a QANTAS pilot with a military background. So I reckon, just a hunch, that there were eye's on what was happening and the fact it ended like this should be a reminder to all to be vigilant..
All you people here having a vent etc, shut your traps and go back to studying BAK.
We'll see what BASI have to say about this one.
