The blades don't necessarily need to server wings, or cut the fuse in half - as it was these passengers were pretty lucky considering the damage this A380 has taken.
Pieces of the engine punched holes through the wing, including one of the fuel tanks, severed the controls of the number 1 engine, tore a hole in in the front spar so big you can apparently put your head in it. Debris damaged the fuselage at the wing root but luckily didn't compromise the pressurised cabin.
At first it was thought it would take at least 2 months to repair - but now theres talk it could be a write off
