Incident: Delta Airlines B763 near Atlanta on Oct 13th 2009, odour prompts returnA Delta Airlines Boeing 767-300, flight DL-101 from Atlanta,GA to Buenos Aires,BA (Argentine), was enroute at FL310 about 120nm south of Atlanta 30 minutes into the flight, when the crew reported smoke in the cabin and decided to return to Atlanta. The airplane landed safely in Atlanta about 20 minutes later.
A replacement Boeing 767-300 registration N154DL reached Buenos Aires with a delay of 5 hours.
Passengers on board reported, that following a normal departure - dinner service was just about to commence - the cabin went dark, the inflight entertainment system stopped working and just the emergency lights at the floor illuminated about 30 minutes into the flight. A flight attendant was observed reporting "smoke in the cabin" via phone obviously to the flight deck. Other flight attendants later claimed when asked, however, that the passenger had misheard and there was no mention of smoke. The airplane turned around and started to descend in a hurry, when the captain announced they had experienced an electrical failure and needed to return to Atlanta. The passengers and cabin were prepared for an emergency landing, however no brace position was ordered. The airplane landed safely and stopped on the runway to have the brakes inspected, a lot of emergency services surrounded the airplane. Later the captain told the passengers in private talks, that he viewed the events similiar to Swissair flight 111 (editorial note: which crashed near Halifax, Canada on Sep 2nd 1998 following an electrical short circuit igniting insulation material) mentioning Swissair several times and he added the incident would certainly make the headlines in all US newspapers. Delta Airlines and the FAA did not respond to the passengers' inquiries over the next month, when they tried to clarify what had really happened.
The NTSB told The Aviation Herald, that an unusual odour was detected on board which prompted the crew to return to Atlanta. Maintenance identified a problem in the air conditioning system, serviced the system and returned the airplane to service. The occurrence is not reportable to the NTSB and is therefore not being investigated by the NTSB, the FAA may however conduct their own investigation.
The Aviation Herald did not receive any replies from Delta Airlines and the FAA within 24 hours after sending inquiries.

There is also an interesting discussion on this thread regarding the passengers 'right to know' about circumstances in an emergency.
Perhaps this one, from a captain (not the captain from this flight), puts the crews' rationale into perspective:

After the accident of Swissair 111 we talked among colleagues and decided: "Smoke of unknown source in cabin or cockpit has to be regarded as severe emergency followed by immediate emergency descent and landing at next suitable field", (whatever ompany regulations or ANYONE ELSE think they have to say to that). Especially since they re-performed the scenario on the simulator with the result that those 220-odd people would still be alive if they had done just that. Going through lengthy procedures as prescribed in the checklist ("Smoke of unknown source" is nonsense).
I lie to the passengers as much as I deem necessary to avoid a bloody riot in the cabin on top of the technical problems I'm fighting against. If they think they have a right to know (especially things they havent't got a clue of), I just disagree. My task is to get them (AND MYSELF)savely (sic) down onto the ground. After that we can talk. If THEY disagree they overestimate themselves, it'the pilots who are flying the thing.

Fritz is rightBy Leo on Sunday, Nov 29th 2009 08:50Z
A perspective from a lay but interested passenger for you pros out there: I agree with Fritz. In an emergency, as much as I'd like to know what is going on, I prefer having the crew 100% focused on troubleshooting and getting us safely on the ground. If a fib is involved I have no problem with that.
I can always come to avherald for the details after we make it safely to the ground.Swissair 111http://en.wikipedia.org/wiki/Swissair_Flight_111
