Disagree--he said 5912 the first time he called when he said he had an emergency (using that word) and smoke in the cockpit and he called for the trucks, and when the distracted controller asked him to repeat, he very clearly said 5912 again. By then the controller had already wrongly concluded that it was a fake call, didn't hear the 59 part of 5912, and pretty much disregarded everything from then on, in his "righteous indignation" at what he believed was a fake call.
Imagine the situation the pilot was faced with, and ask yourself if you could calmly state everything: There's smoke rolling out from under the panel, you have seconds to get the airplane on the ground, and you have a controller who frankly isn't paying much attention. Your panic level increases, a normal human response. Not only are you at risk, but you've got an airplane full of passengers who are counting on you. But you can't even get the controller to acknowledge that you're in trouble. You don't know if there are other airplanes that will be in the way as you turn back to land, because the person who is supposed to hold all traffic for an emergency is not even responding to you. But you land successfully, and you do your job and evacuate the passengers--but you still try to get the controller's attention because you know you might have passengers with injuries and your airplane is on the runway--and the only mike is in the cockpit where all the smoke is coming from. Maybe you'd be screaming, too.
Sorry, I can't stand up for the controller at all in this case. At the end of the day, he gets to go home to tell his wife that some of the pilots weren't very professional--they even shouted into the mic so that he couldn't understand them. Never mind that he was so asleep at the switch that he couldn't tell a real emergency from his imaginary bogus one.
I can't be sure because it's been almost 2 years, but the voice of the controller sounds suspiciously like a Denver Approach controller who used non-standard language with me so that I couldn't be sure if I had been cleared into the Class B or not. When I asked for clarification, I was screamed at by the controller, and there was no more call for that than what happened here.
99% of controllers are good people, doing their job. But like all professions, there are those who are substandard and who really ought to find another line of work--one with no hassles, no pressure, no contacts with people. I think this may be one of them. At the very least, he needs some heavy duty remedial training.
