It was full of what looked like sparks that spread out quite fast behind it but also faded fast. Sort of like the rough part of a wake behind a speed boat. It was incredibly bright, but very very short in duration.
Terminal flash

No
Remarks
If by fragmentation you mean the spark-like effect I saw, then yes I saw fragmentation. It was like seeing the sparks fly off from a sparkler (4th of July) or similar fireworks.
