Based on my memory, the aircrew went to idle on that engine a couple minutes before the "bang". I was checking my watch thinking they had pushed their speed since we were a little late getting out of Atlanta, going to my phone to see estimated flight time (no Flight Tracker on the MD88), and had started initial decent. When the bang happened, I kind of forgot all that. So, wait for the report, but my guess is they got a warning, pulled to idle, were running the checklist for the indication when it happened. The good news is that all the parts should be available for P&W to do their teardown and get to root cause.
