families who have already been briefed about this. how hard it is for them to take in. especially given the fact ththey knew the expertise, the ceo, was on there. the man who s been called mr. titanic down there more than 30 times. the french marian, p.h. nargeolet. they heard noises that could not be explained thought perhaps there was a chance. this tends to indicate that what they are being told by the u.s. coast guard, this debris who been found. there is still a lot more to do here in terms of to find this submersible and understand exactly what happened. again, we continue to reach out to canadian officials and i will say the transportation safety board here in canada would be in charge of any investigation and at the ready and again deployed so many assets there in terms of recovery. they will be able hopefully to give those families what they need, which is information and peace of mind.
