A rationale for course of missing plane?

Richard Fernandez:

One of the reasons adduced to support the theory that MH370 was purposefully flown is its maneuvering. Here is the supposed track of MH370.

Track

Now here is the same track overlaid on the civil radar coverage apparently taken from Skyvector. It is suggested that the track shows an aircraft trying to stay out of radar coverage.

Evade

You don’t have to buy this analysis. First of all, I’m not sure the waypoints are accurate. They are only as reported in the press. Second, it is far from certain the route taken minimizes exposure to primary radar, which the putative bandit would have been trying to avoid at this time.

But it give one a sense of the reasoning behind the claim that a malevolent or at least purposeful intelligence was guiding the motions of MH370 that fateful night.

There is much more.

That last little jog seems to have taken them off most radar screens.  I doubt that most terrorist are smart enough to do this, but a trained pilot probably would be aware of how to avoid radar coverage.  I suspect it is another reason why the pilots have become the focus of attention.

The plane also flew at 5,000 feet to avoid radar detection.
