Sailvi's summary does not appear to match 100% with what Simon reported the Spanish authorities said:
"On Dec 11th 2013 the CIAIAC reported the aircraft blew a right aft tyre during takeoff from runway 36L, debris of which impacted the lower side of the wing and causes a hydraulic failure preventing the gear from being retracted. The aircraft landed on runway 32L. After landing the aircraft vacated the runway via the last rapid exit taxiway to the left and stopped in a grassy area about half way between runway 32L and Terminal T4 with all 8 main tyres being flat. The aircraft received substantial damage to the right hand wing including the loss of internal and external components as well as to both engines due to ingestion of stones during the excursion from the taxiway."
So did they veer off the runway directly or did they take the last rapid exit and then went off-road?
