Some similarity with the South West secondary events. The engine itself does a good job of capturing the high energy blade pieces. Unfortunately some of the blade pieces find their way forward of the containment belts and chew into the soft inlet. with a big slashing effect. If the slash gets very long circumferentially then the cowl becomes limited in vibration. looking at the various video feeds on the nws, the shiny front lip of the cowl can be seen after the initial event still attached. Later on in the flight it is now missing.

It is not good that the engine nacelle (reverser) caught fire. The smoke behind the engine does not match a fuel fire and neither does the flame color in the videos. Quite possibly the non-metallic vanes in the reverser are what is burning. The ability to extinguish this in flight is challenging, but at least the slip stream keeps it away from the wing spar. I would be interested to know how the fire fighters addressed this on the ground.

I suspect there will be a few lessons learned here
