A turbine disc fragment ripped through the entire plane cross-section and exited on the other side. Stunning.

I like the pragmatic engineering point of view described in the article:

> For engineering purposes, disk fragments are assumed to have infinite energy at the moment of release; they will cut through any reasonable material and cannot be contained.

  • Also demonstrated by the picture in the op of the brick wall. Note that it wasn't smashed or knocked down, but looks as if it was cut.

    • That must have been the section that broke downward, so was traveling faster than terminal velocity.
