LLD. Thats exactly what I thought but if you take a look at the pics you can see quite a large dent in the lower ventral fin...pretty sure the flip would not have caused any damage to the lower half of the aircraft unless the whole tail section has moved downwards due to the impact of the tail fin on the sandbar (ie bent spine). Am surprised that the pilot did not notice a lack of performance during the takeoff and abort sooner (as CC stated it must have been like towing a sea anchor).
As for the pilot getting back in the air...unfortunately, post accident the considerable rise in insurance premiums are usually the deciding factor.
