I was guessing upper for failure.. Then punched the window and then broke at the crank. I just wonder off the flip had anything to do with it? Like over reving upside down? Great vid!
You're missing a rod bolt - it could be a connecting rod bolt failure. That would also be consistent with seeing minimal damage to the rod journal and cylinder wall.
Shout out to @spencergiles72 for all the great feedback!!✌

So I had to repost this vid. Previous version had some comments about how the rod bolts can come loose which may be the cause of the failure.
