Someone at Delta Air Lines informs us that the Airbus A320 flown by Northwest Airlines on Flight 188 had a 30-minute cockpit voice recorder.
If so, that would mean that any portion of the recording that may have included light snoring and murmured dreams would have disappeared long before the crew pulled up to the gate in Minneapolis-St. Paul on Wednesday night.
If the recording stopped the moment the airplane pulled up to the gate at 9:15 p.m., that means the CVR would have taped only the portion of the flight that came after the pilots had begun responding again to air traffic controllers.
I hoped they argued a little about airline policy to back up their story.
