>> james, you can't survive in that cold, if you are not reached by the rescuers, right? >> absolutely. it doesn't bode very well. there have been unconfirmed reports from media about some parents, at the scene of the accident, using -- online based messaging services on their phones to contact students who might still be trapped underneath the hull. but unfortunately none of that has been confirmed yet. and very difficult to go on from there. >> briefly, anything they're going to be doing in the next several hours here in terms of priorities? >> prior to the minutes moving in two large cranes to try to raise the wreckage as much as possible. beyond that, they're waiting for the tide so, they can start pumping air into the remaining air pockets. you have to worry about hypotherm hypothermia, and also being stuck in an airtight space under the ocean. >> certainly. james pearson. thank you for your reporting. stay safe out there.
