A Singapore Airlines flight from London to Singapore made an emergency landing at Baku in Azerbaijan, Eastern Europe, about six hours ago.
The Airbus 380 was forced to divert due to cabin depressurisation, an SIA spokesman said on Monday. Oxygen masks were deployed and the aircraft landed safely with no injuries to the 467 passengers and 27 crew on board, he added.
The spokesman said: "We are seeking clearance from local authorities to transfer affected customers to a hotel until a replacement aircraft arrives from Singapore."
In a Facebook post, passenger Matthew G. Johnson claimed that shortly after take-off from Heathrow airport, "a loud air noise was heard from the door five rows in front. So loud it was impossible to hear and cold due to the airflow". He questioned the crew who allegedly told him about two hours later than the door had a "mild" leaking seal. Another few hours went by before this led to cabin depressurisation and forced the emergency landing.
