not actually true....I know for a fact (since I know people that arrange the insurance for IAG) BA did a deal with the insurers, who paid out a compromise amount, which means BA retain the "salvage".
BA then BA would, via the loss adjusters appointed by insurers, have contracted a firm to break up the aircraft and sell the useable salvage.
BA will presumably have shipped many of the internal fitting back home, since the seats, avionics etc will be useful to them in the rest of their fleet, they may have taken the engines home, but may have sold them depending upon how many spare engines they already have in the fleet.
The rest, well as we can see....backed bean cans....
