Was that the lavatory fire? . . circuit breaker procedures?
Yes, it was. But it was more than the circuit breakers, there was a breakdown of reliable communications between the cabin attendants and the captain. At first, NTSB found fault with the flight crew (1984), but after a redress and petition by ALPA, NTSB revised their report (1986) and exonerated the crew actions.
The critical gap of four minutes between 1904 and 1908, when the emergency descent was initiated, was all the difference between getting the plane down sooner (Louisville) rather than later (Cincinnati).
