I thought the same as you re: hit at an angle. This makes me wonder if it really hit a geologic formation of some type. It suggests the possibility of another sub. I doubt we'll ever know. If she hit an undersea mountain, then I think she hit at 55-70 degree angle. How?

Well US subs NEVER use active sonar unless they are spotted by the enemy. So there is no way they could have "seen" the seamount.

" So there is no way they could have "seen" the seamount."

What if a foreign chased sub knew the seamount was there, knew that our charts were deficient and led us in.
