@ A0283...
Not an expert but if as you suggest the aircraft "went straight in" then one would have to assume it is not in a "stalled" condition, thus probably hitting/entering the water at a substantial speed.
In this case it would most likely break apart in many small pieces upon hitting the water almost like hitting solid ground.
