Details have been gradually emerging about the disappearance of an Air France flight from Brazil to France in the early hours of Monday 1 June.
Flight AF 447 left Rio de Janeiro, bound for Paris, at 1900 local time (2200 GMT) on Sunday.
The aircraft, an Airbus A330-200, had been in operation since April 2005.
Shortly after the aircraft's scheduled arrival time in Paris of 1110 local time (0910 GMT), it was announced that the flight was missing.
Here are the latest developments:
WEDNESDAY 10 JUNE
The French nuclear submarine Emeraude - equipped with advanced sonar equipment - arrives at the crash site to search for the flight data recorders.
TUESDAY 9 JUNE
Brazilian officials say a total of 41 bodies have been recovered.
The first 16 bodies found over the weekend arrive at the rescue base at Fernando de Noronha, off the coast of Brazil. The other 25 are due to follow.
MONDAY 8 JUNE
A Brazilian search team recovers a large tail section - painted with Air France colours - from the ocean.
The navy says about 100 more objects have been spotted in the crash zone, including seats with the Air France logo and oxygen masks.
SUNDAY 7 JUNE
Fourteen additional bodies are recovered over the course of the day, taking the total to 16.
Air France says it is accelerating the replacement of speed monitors on Airbus planes, amid speculation that faulty data on the old-type sensors may have caused the crash.
SATURDAY 6 JUNE
1700 GMT: The Brazilian air force finds the first two bodies from the area where the plane is expected to have crashed. In addition to the bodies, a suitcase and backpack are found, along with a seat from the plane.
The items are the first to be definitely linked to the plane, nearly six days after the crash.
THURSDAY 4 JUNE
2100 GMT: Brazilian air force retracts earlier statements, saying debris collected from the sea - including wooden pallets and buoys - is actually just "sea trash". It also says a large fuel slick is probably not related to the plane.
WEDNESDAY 3 JUNE
1400 GMT: A Brazilian air force spokesman says more, larger items of wreckage and a fuel slick have been spotted by air crews about 90km (55 miles) south of where other debris was seen on Tuesday.
0900 GMT: A French aviation official says he is not optimistic the plane's flight recorders will be found, given the depth of the ocean and the undersea terrain.
There appeared to be no problems with the plane at take-off, Paul-Louis Arslanian says, but the exact time of the crash is not known, nor whether the chief pilot was at the controls. An initial report is expected by the end of June.
