Oh, and I forgot to mention the geo-political angle.
There are a number of countries with dogs in this race. As I know from experience, governments are ruthless. They will not care one jot for the feelings of the families of the pax and crew. Not one jot. I have seen people's characters destroyed for the 'national interest'.
Governments will do whatever is best for their own interests. Whatever they say publicly should be treated with healthy scepticism until the aircraft is found, if it ever is found. If one of them wants that aircraft never to be found, it will probably never be found.
That's the reality of how things work, however distasteful it is to the honourable and decent amongst us.
