Sick planes

Qantas' A380s seem to be sick. Here's the 2nd incident that the plane had to return to Singapore just after takeoff. Lcukily there was no casualities for both incidents.

3 years ago, I met a friend whom was sent here to check on Rolls-Royce engines, it was the time when A380s were newly introduced and the first fleet of A380s were for Singapore Airlines. Now I hear that they need to investigate this issue on Qantas A380s and it might take a year. Who knows, maybe my friend will be back to work on it? Or maybe not. Just a random thought!
