Despite all the talk of the Cabri engine potentially quitting, it doesn't explain the seemingly high impact crash and fire.
I would have thought with his level of experience that an engine out auto would have been reasonably successful.
This looks like it plummeted in from a height, which I would have thought points to either catastrophic mechanical failure or medical incident.
The reports of someone bailing out could point to in flight breakup and parts falling to earth.
Be interested to see what the AAIB find.
