Heard on the radio this morning, unconfirmed, that the families have been informed of the possibility of the wreckage being located. They then went on to say that previous sonar returns of large objects that might have been wreckage, were in fact found to be large logs or boulders on the bottom. The divers are working in trying conditions with strong currents and visibility reducing to 1 metre. The search area being 12 square kms.
Might have more info by the end of the day. Hope that helps
cheers
