facts and presumptions
The first time the pilot speaks about emergency he says: "if you don't give us 31R we are going to declare an emergency". The second time, after the controller tells the pilot to continue runway heading, he says:"OK, we are declaring an emergency to land 31R...". When the controller confirms the emergency the pilots responses: "Three times we are declaring an emergency...". The fact is that, before that last transmission, the pilot only once actually declared an emergency, the first time he said he was going to declare an emergency if he was not cleared to land on 31R.
Furthermore everything else is a presumption, because we don not know the actual reason for the emergency.
I really hate it when people start judging and blaming only on presumptions!
I would expect people that are working in aviation themselves to be more detached.
