Re "I can't remember ever seeing a high bypass jet engine, after hitting the ground with such force as to rip it off it's pylon..."
As has been discussed on other threads, Boeing engines are attached with "fuse pins" designed to allow them to separate in a case like this.
It's to meet an FAA requirement that "large masses" should not cause further damage to what remains of the plane. Especially the pax cabin.
