There surely was wobble here, however brief, and the last part of the fan case to let go might largely determine the ultimate trajectory, do we think?
FWIW - agree with the above but must also include gyroscopic action to the trajectory calcs. Observation of the phot showing leading edge outboard **seems** to indicate fan and part cowl departed down and to the right. However, IF it went above the wing, seems to me to be a fair chance it would hav hit or dinged the right horiz stabilizer. I'll bet a detailed analysis after full examination of parts and external dings will provide a better trajectory analysis AND why-where fracture started
