Snowfalcon2,
Will they continue search for the CVR, or is the FDR important enough for the ship to head for port? Or are there other ships in the area that can transport the FDR ashore?
I think I remember to read somewhere that a frigate or other ship would be used to transport the FDR and the CVR to the continent.
Both equipments are too important to they dare to transport it by chopper. Besides, I think that the Ile de Sein has not an helipont.
