Had a look at the blade(s) after the fact, and found out where the significant cascading sound comes from when the brake activates. 12 separate tungsten carbide teeth ripped loose of the blade. Most presumably are due to the spacer blades not being in direct contact with the aluminium brake, so were able to move when the blade was (rapidly) decelerating, and knocked the teeth off as they slid past.
It is a good effort, stopping that much spinning steel on a dime!

Wow, that is a pretty violent stop. You can see the whole carriage shaking when in slow motion. Very very impressive.
What freaks me out the most is the dado in the frankfurter. What happened to the missing bit? Was it atomised? I guess you won’t be getting anything sewn back on at the ER if that happens to you.
Me too- that blew my mind thinking about the damage it inflicted. The missing bit is not some piece somewhere, it is just gone in a spray of DNA (to be horrifically poetic!!!)
