It is always inconvenient when a passenger dies on an aeroplane - not least for the person sitting in the next seat. So Singapore Airlines has attempted to take the trauma out of such tragedies by introducing a special cupboard to store any unexpected corpse.
The airline's new fleet of Airbus A340-500 aircraft boasts a discreet locker next to one of the plane's exit doors which is long enough to store an average-sized body, with special straps to prevent any movement during a bumpy landing.
Cabin crew have been instructed to use the locker in the event of a death on a long-haul flight - particularly if the aircraft is busy, with no free seats on which to lay out the deceased.
The aircraft came into use in February, operating the longest non-stop route in the world: a 17-hour, 7,900-mile journey between Singapore and Los Angeles.
The length of the flight has forced Singapore Airlines to think carefully about its handling of any medical emergencies - particularly because the route spans the Pacific Ocean, with little opportunity for an unscheduled landing.
An airline spokeswoman said: "On the rare occasion when a passenger passes away during a flight the crew do all that is possible to manage the situation with sensitivity and respect.
"Unfortunately given the space constraints in an aircraft cabin, it is not always possible to find a row of seats where the deceased passenger can be placed and covered in a dignified manner, although this is always the preferred option.
"The compartment will be used only if no suitable space can be found elsewhere in the cabin."
The airline intends to begin a second route next month using the same long-range aircraft - the flight between Singapore and New York will skirt the north pole, offering equally little scope for diversion.
Richard Maslen, the assistant editor of Airliner World magazine, said the compartment was an interesting feature of the new aircraft, which seats 180 people.
"As far as I'm aware, this is not something that's been thought of in other aircraft designs in the past," he said.
"Obviously, these things do unfortunately happen in the air and it's good to see that they have been thought about in advance."
