This appears to be the aircraft. It also had a littler kit so no baggage compartment to deal with. Fire/smoke seem to be coming from the bottom aft corner of the engine deck. And given the angle of deck this is where any fluids would be gathering at. It also looks like the tailboom failed aft of the mount flange where the structure is mainly carbon layers and nomex core. Something not very fire proof or excessive heat resistant. Hopefully all the data modules survived the post fire and will give a picture of what transpired so quickly.
