Cousteau did use the Denise sub on the Niagara when here. We had a Triton sub dive project set up for the past weeks to dive the Niagara but on hold due to the Covid-19 situation. Both divers were involved with the Thai cave rescue - Harry was the Doc who sedated the boys and Craig assisted with diving them out - they have recently co-written a great book on the rescue well worth a read. You wouldn't get far with a Exo in the Pearce cave system.</div><div><br></div><div>Cheers</div><div>Keith Gordon</div><div><br><div><div>On 5/04/2020, at 10:46 AM, Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><meta http-equiv="content-type" content="text/html; charset=utf-8"><div dir="auto"><div><span></span></div><div><span>Hi fellow submariners,</span><br><span>A caving friend asked me if I had a submarine that could dive the cave in the link</span><br><span>below.
