My Army unit heard the tape as part of a safety class given by D.A. Civilians. The class consisted of an in-depth analysis of the accident. I don't know if it was ever released to the public.
My recollection is over 20 years old, but it was hard to forget. The pilot's tone and tenor was disturbing. He was an individual in a complete, total panic. His words were plaintive screams. ATC would offer assistance ("What do you need?" "You are clear to procede however you like.") I'm not sure the pilot made more than one or two coherent reponses. Usually silence, punctuated by occasional screams "Emergency! Emergency!"
One of the barriers to releasing the entire class to the public was the fact that they dug up the LT's training records and showed him barely passing any phase of the training. His biggest problems came during instrument training.
