Justo some rumors I heard from Alitalia maintenance crew, wich had to replace the engines on the affected aircraft.
- As mentioned many blades were damaged on both engine.
- One engine had to be shut down at some point, the other one, was only able to give partial power
- crew started to dump fuel, but with both engines damaged they decided to come back immediately, with a 10 tons overweight landing.
- Due to the excess of braking required due to the higher weight/speeds but also as they were not able to use reverse most of the main landing gear tyres blew up...
hope can help the discussion...
