<div dir="ltr">I did some digging - 96 hours of air, but it's already been over 24 hours since it dove. It had pings it sent to the launch vessel at regular intervals which stopped and then no contact since then. It should be noted that last year a CBS reporter dove on this very sub and they 'lost contact' for some six hours then. <div>They also have seven different methods of emergency flotation, some of which are quite ingenious. They have the usual: an inflatable flotation bag, hydraulically released ballast, and they also have bags of ballast on fusible links that the salt water severs after about 16 hours. They also have roll-off ballast bars on the sides. They literally get everyone on one side of the sub so that it leans, and the bars of ballast literally roll off the shelves - they're only held on by gravity.. Roll them off both sides you've gained a lot of buoyancy. They can also jetison the legs which is a lot of weight and there's ballast bags that are electrically released. </div><div>However, if they float to the surface, they are still sealed inside, bolted closed from the outside. </div><div>But still - this does not sound good. Contact was lost about 1 hour and 45 minutes into the dive, so it would have still been descending.</div><div><br></div><div>Ian</div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jun 19, 2023 at 5:16 PM Douglas Suhr via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">I'm sorry to hear this news.
