That's unlikely. The pilots reported discrepancy in attitude and speed data between the left and right MFDs. This is almost certainly an instance of MCAS activating due to erroneous AOA data.

 &gt;Yeah tower, this is Captain flight E-302, getting some major push back.   
 &gt;   
 &gt;\-Copy that, disable MCAS and level out.   
 &gt;   
 &gt;Negative tower, I say again, this plane is giving me some really bad attitude. I recommend we put this bird down for a nap.
