HI DAN, It was hard to tell if the headset went first or it all happened at the same moment. There were two of us E4s that C/Cd that plane (491) and at the time it happened (after midnight) I was at the hootch. When I was leaving for the flightline around 6 in the morning, the other C/C was sitting on his bunk and still in shock, he was sitting erect and with a blank stare on his face. The word was, when Tim was performing the engine trim, that the C/C heard the flameout and immediately shut down the left engine and looked out the window and saw the cord to the headset leading into the intake. He climbed down, thinking the engine man lost his headset and left the area immediately due to the noise. When he looked into the engine, he then realized it was the man himself and not just the headset. I had the erie duty the next morning of helping the engine shop change the engine. The plane crashed on landing less than a month after that. There were run-up screens but only the close mesh cone type that were insufficient at high engine speeds. And, you're right, the next day the cages came rolling onto the flightline. I heard (not confirmed) that Tim himslef had suggested the cage type run-up screens because he realized someone was going to get hurt, due to noise fatigue.
I'm on vacation in Dallas right now but will send you some pictures when I get home.
