I would not expect to hear from a pilot fighting a cockpit fire - especially one that he ultimately losses. He can only breath through his mask and he may not be able to see beyond that mask. Given the environment, there is no assurance that the pilot was even conscious immediately before the impact.
And if he was, there is nothing the outside world could have done to help him.
