It can be wise to let an airline go bust if it has large debts, as Malev did. Then you can start new with a clean sheet for the future. Is this not the case here? As I just heard that the Hungarian government has stated that it has hopes Malev will make re-start. This might have been just a clever way to get out of paying back the state aid Malev received and clear all debts.
I really hope for all the people involved a re-start will be possible. I have been involved in a bankruptcy myself before and it is far from nice. Good luck to all there in Malev.
