Interesting...
I remember @Goldie mentioning something about a Singapore to Barcelona flight, SIA68, that was in the skies nearby at the time. (Think her post was on 12/3 in a previous thread)
Seems MH370 "piggie-backed" right behind on this one to evade radar.
The flight path would have taken it right over India northwest-wards.
If so the plane could be somewhere in central Asia/ Iran etc on the ground... waiting... for who knows what

Think this is a very plausible scenario, and if so, shows very deliberate and meticulous planning.
