INFO LE FIGARO - La campagne pour récupérer les boîtes noires, les débris de l'appareil ainsi que des corps de victimes devrait débuter dans trois semaines et sera intégralement financée par l'État. Lire la suite l'article
Localiser l'épave de l'AF 447 n'était que la première partie de la mission. Les membres de l'enquête de sécurité aérienne qui ont retrouvé l' AF447 ce week-end dans l'Atlantique sud , vont circonscrire le champ de débris et prendre de nombreuses photos avec les sous-marins d'exploration Remus. Objectif: localiser les différentes pièces de l'appareil ainsi que les boîtes noires qui permettront de lever le mystère de la catastrophe aérienne. Cette campagne, la quatrième de ce type, a été financée par Air France-Airbus, à hauteur de 9 millions d'euros.
Selon l efigaro.fr , la cinquième phase, celle du repêchage des boîtes noires, des débris de l'appareil ainsi que des corps des victimes, devrait «débuter dans trois semaines», de source ministérielle et devrait coûter 5 à 6 millions d'euros. L'Etat avait déjà lancé la procédure d'appel d'offre dans la perspective d'une probable localisation de l'épave et les étapes de la consultation devraient s'enchaîner rapidement.
Les premières photos envoyées par le navire Alucia, dans l'Atlantique sud, montreraient des morceaux intègres d'appareil et plusieurs corps de victimes encore identifiables. La profondeur (-4000 mètres), la pression et la température de l'eau auraient permis de conserver les corps des victimes. Les fonctionnaires en charge du dossier réfléchissent donc à envoyer des moyens spécifiques pour repêcher les victimes ainsi qu'une cellule d'identification. «Remonter les corps d'une telle profondeur, après deux ans de séjour dans l'eau, sans les endommager et en évitant la corrosion des eaux chaudes en surface relèvera de l'exploit», selon un proche du dossier.

BEA press conference
1. The debris field exact location is not to be disclosed (in the North West large abyssal plain about 10 NM from LKP) for security reasons.
2. The debris field was first identified yesterday night around 19.00 (Paris). Its size is about 600 x 200 meters (including both engines, cabin, wings, landing gears).
3. The Remus were sent back to take some pictures of the field, cruising about 10 meters above the wreckage. The sea botom is flat and soft, made of sand or vase. Parts of the landing gears appears to be sinking into it.
4. Actually, the Remus are used to make a complete photographical report including geo-localization of all the wreckages (quadrillage). This would take several days to complete this work.
5. The bodies found would be recovered in the next phase. The main goal now is to find the recorders, still to be found.
6. Next phase will start with a new ship using ROVs, funded by French government, in order to recover the findings. It should start in about 3-4 weeks and 3 ships have been offered the job (one from France telecom, one from Alcatel-Lucent and one from a US company).

A short video of the interview with the Environment minister here:
Bodies found in wreckage of 2009 Air France crash in Atlantic -
I think perhaps the three weeks may be the time to get the three ships underway or enroute. It would be pretty quick for the ships to be on station and recovering in three weeks time, unless they were already in Brazil or the Azores.

and cost of the recovery will be 5 million Euros, to be paid for by the government.

Thank you Machdiamond. I was relying on my A Level French which is now so rusty it is probably verging on becoming a pile of dust.

What could be recovered for 5M€? Surely not the wreckage itself? From the press articles, though, that sounds to be the intention. I'd have thought they'd leave the poor souls and just try and recover the recorders, but it seems they actually want to recover the fuselage?
Second thought: How will it be done? Is there a capable successor to the Glomar Explorer that'll be able to salvage stuff from such a depth?

Anyway, maybe best to leave the poor souls where they are, and concentrate on the data first

Pitot tubes would be worth a look, just as was the case in the Aero Peru & Birgenair crashes in 1996.

This AP report mentions what pictures were shown at the press conference (does not show them). Otherwise it does not contain much more information than what takata already posted.

keitaidenwa, how do you know the exact location where the main wreckage has been found was searched during the previous phase? See mm43's maps which indicate there were gaps in the previous searches, and the first task for Woods Hole was to search the areas near the LKP that had not been searched before.

1. finding and recovering the flight recorders;
2. finding and recovering the maintenance computer;
3. recovering the passenger bodies;
If needed (in case those recorders canot be exploited to fully understand the crash) any other pieces of the wreckage that could be usefull for the investigation to understand the crash would also be recovered.
Detailed pictures in situ can also tell a lot to the BEA without the need to recover all of them.

My mistake then.. I was under impression that northwest directions specifically were already searched.

BEA Pictures
In case no one else has yet posted this information, here is the link to pictures shown by the BEA on its web site:
