Why would they initiate such an "evasive action" at 02.10 while they had to keep flying "pitch and thrust"?... this would not be very smart without a real need to do so. During all the similar sequences documented so far (more than 36), not a single crew did take such an initiative to make an "evasive action" only due to unreliable airspeed data.

Nothing is telling us for sure that the aircraft impacted at the end of the ACARs transmition (02.15). In fact, without engine power, no more ACARs would be sent anyway.
Given the approx location of the debris, is the fact that the 02:10:30 (assume this is exact time of position acquisition, transmission 4s later) location was "slighty west 3NM" of track INTOL - TASIL now more significant.

Yes was discussed at length previously, and can only be answered for sure by the black boxes - but was the deviation deliberate or indicative of an earlier upset?
