Wouldn’t more of the wall be destroyed? Or the angle of the barrel changed after the initial penetration?
Not speaking to the authenticity of the photo, but if cinder blocks aren't filled with concrete they aren't exactly super puncture resistant. They actually aren't all that hard to punch through.
I doubt it's very easy to move the barrel externally so I'm surprised the wall is there at all. It's probably even supporting part of the tank's weight somehow.
Honestly best place it could have hit. Didn't damage the door or even the control conduit. If they don't do more damage backing up it won't be a complete disaster.
That doors not high enough either. Even if they'd managed to find the giant hole in the wall the whole thing wasn't gonna fit.
