It did take along time to repair, even the Russian FAA has standards. The Russian FAA refuesd to allow the aircraft to be bojjed and said it had to be fully servicable before it could overfly Russian FIR. It took so long as parts are not readily available for An124's and they all had to be flown in.
Heard from an insider that no confirmed reports of how big it was and how long the fire burnt, but as stated earlier a number of guys are confirmed to be injured from having to jump from the wing and fuselage.
