    Could there be any other vessels that sunk there in the past, responsible for a debris field?  Not familiar with the Northern Atlantic there, but it's not inconceivable that it's just from a ship that sank there, say, a hundred years ago?

    It was found near the wreck of the Titanic but it's implied that this is a new field of debris. The Titanic's debris field is very well studied;

    The HMCS Glace Bay is reportedly heading to the search area with a diving bell of some kind and a medical team. I've been on the Glace Bay once before, she was docked in Hamilton and they allowed civilians to walk around her. She's a nice little ship, I trust her crew will do their best with the little resources they have.

    Reportedly the companies CEO is on board as well. This is well and truly a disaster on all fronts.

    By who? It's not like the wreckage is patrolled by the International Waters Sea Police.

    There are treaties in place and this is a public mission. Not that there's anything rock solid protecting the wreck. It's been looted quite a bit sadly but I do not believe the Titan can even pick up artifacts.

    We now know the likely identities of two more customers. Pakistani businessmen Shahzada Dakhood and his son. Yikes, this is an ugly story so far. I still hope for a safe return but we need to prepare for the worst.l now.

    wouldnt they have heard a big crash on sonar if they hit the wreck (or vise versa)? planting into the silt would have made less noise, but enough to spike on sonar. an implosion would have also made noise. 

    I do not believe there was any sonar equipment in the area until the USCG was called in several hours later. If there was a sound it was missed, maybe it was picked up by a more distant sensor but it's a remote area.

    how close to the wreck were they allowed to go? 

    Pretty much right alongside it, a collision or ensnarement is one of the likely explanations for the loss.

    I'm curious; if the dive down takes around 2 hours if they make good time and the last ping heard from it was at the 1 hour 45 minute mark is it possible they went down too quick and hit bottom or the wreck due to a miscalculation or an issue? Keep in mind the pings normally come back every 15 minutes.

    I know the USCG is onsite as well as Canadian assets, but I'm surprised that the USN hasn't been called in, as far as I've heard. I wonder how long it would take to get another deep-sea submersible on site? Come to think of it, I'm surprised they don't carry two submersibles for just such a contingency, even if one is just remotely operated

    If you end up in a situation where you need a second deep-dive sub then you're pretty much screwed. It's almost impossible to approach and dock with anything at that depth. Let alone a situation where the first sub is disabled and lying at a weird angle. If they're on the seabed then as bleak as it sounds it's better to hope that they didn't suffer much.

    Since they were near the two hour mark when they were last heard from It's possible they could have hit the wreck during or just after descent. That is a truly horrible way to go, especially if the wreck came down on them. If their still alive at this point they don't have much of a chance if they aren't bobbing on the surface somewhere, just too deep to even think about a rescue attempt.

    The Titan Submersible has gone missing with 5 people on board while diving to the wreck of the RMS Titanic. The sub is owned by OceanGate Expeditions which conducts yearly visits to the wreck to study the remains as it decay's. It also brings along tourists to help fund their efforts. The Titan carries 2 main crew members and 3 others, usually high paying tourists. One of these was rumored to be Blue Origin customer Hamish Harding who flew to space last year. The dive takes around 8 hours, 2 hours down, 4 hours at the wreck, and 2 hours up. The Titan dived down sometime Sunday. The sub last pinged around the 1 hour 45 minute mark after which it hasn't been heard from since. The US and Canadian coast guards are searching for the sub on the surface but it has yet to be found. A statement will be released around now from the coast guard, this is a developing story, some details may be incorrect. Lets hope for a safe return for the crew!

    Some details about the sub;

    6.4 Meters in length

    4000 Meters max depth (Titanic wreck is at 3800 Meters)

    5 Man crew capacity

    96 hour oxygen supply (with full crew)

    Pings location every 15 minutes usually.

    The wreck of the RMS Titanic has been fully 3D scanned. For the first time in 111 years we can view the entire ship;

    Scan of bow of Titanic

    The bow is the last intact piece of the ship. When the vessel broke up the bow cruised away from the rest of the wreck and lies 600 to 800 meters from its stern. While the bow is starting to decay it at least looks recognizable as being a ship.

    The bows port side is showing signs of collapse.

    The large hole in the deck is where the grand staircase was once located, being made of wood mostly it was torn apart as the ship sank.

    Stern

    The Titanic's stern is totally collapsed. When the section sank it had not yet filled with water and it imploded as it sank. It also probably tumbled through the water at twice the speed of the ship's bow before corkscrewing into the bottom. Whatever was left of the stern has since collapsed and been totally flattened. The vessels fantail (end of the ship) is beginning to sag downwards and what's left of the ships engines is now taller than most of the vessel.

    Another view of the collapsed stern.

    The ships starboard propeller. When it hit the bottom the central prop and rudder were buried and the side screws were bent upwards at an angle of about 20 degrees.

    The scan's detail is incredible, here we can see a serial number on the starboard prop.
