consider this though, flying through a volcanic ash cloud ( There are current eruptions in the area) could have eroded off various comm and transponder antennas to a point of rendering them incapable of transmitting.

something to think about

It would have been dark... and ash does not show up on radar. The first indication of entering it would likely be static discharges and st elmos fire

Well as CCIP stated above even if the thing was fully fueled it would already be on the ground one way or another by now. Also aren't flights supposed to be routed around Volcanic ash and even be grounded if the circumstances call for it?
