It's Not Logical Jim.
@Sky9;- Just because the a/c wasn't seen on Radar doesn't mean this was deliberate or planned. Radar coverage is patchy and as has been oft-repeated in this thread, several Governments in the area wouldn't want to admit how poor the coverage of standard of watch is. Hardly surprising then, - but to extrapolate from this fairly predictable fact that the routing was taken deliberately to avoid the Radar is pure speculation. Sure, one can have any pet theory one wishes, but Radar-avoidance is NOT a proven fact, just one more theory.
