@Sir Richard #10929
Approach to PEN. Given decent cloudbase and surface W/V, a no-radio approach to R/W22 would be preferable. Not sure that they would have any on-board nav receivers remaining, and there are bits of dark forested hills just N of the approach to R/W04. All the lights of George Town are available for a sraight-in app to 22.
Whatever, we do know that they didn't land at PEN.
Any overall explanation of what went on has to include the Inmarsat curved position lines and, I believe, the reports from (several) fishermen at sea and others along the coast to the south of Kota Bharu. No-one has yet explained how the radar traces etc can be positively attached to MH370, except on the basis of 'well, who else can it have been?'
