engine separation
Too early to speculate on how/why aircraft veered to the right. No facts on what engine actually came on fire.
If ... still beeing speculation, one engine totally separated this would most likely change the center og gravity of the plane so far forward that it would be impossible to control in pitch .... so if airbourne the aircraft would be forced into descend/uncontrolled landing .
Know of a DC9 that suffered severe damage to eng attach points after hard landings, but no clues if this has happened to MD's at all.
