An official report has failed to solve a mystery aboard a flight from Dublin during which many passengers inexplicably appeared to pass out shortly after takeoff from Dublin.
The crew aboard the Cologne-bound aircraft were so concerned that they donned oxygen masks and declared an emergency after travelling just 30 nautical miles off the coast in May 2008.
The alert was triggered when the purser told the cockpit that almost all the passengers had fallen asleep after the plane passed through 10,000 feet.
However, nothing was found to have been wrong with the aircraft, and some of those on board said they had experienced nothing unusual.
The investigation did however call for better medical services at Dublin, as no doctor was available to assess those on board when the aircraft safely landed.
