According to Wikipedia:
If no control inputs were made following flameout and the disengagement of autopilot, the aircraft would likely have entered a spiral dive and entered the ocean within 20 nmi (37 km; 23 mi) of the flameout and disengagement of autopilot.
Does this mean the autopilot automatically disengages when both engines experience flameouts? If so, how likely is it it would enter a spiral dive within 37km of the flameout?
Are there any other control inputs the pilot could have made before flameout that would cause the plane to glide until it impacted the water?
