An underwater video released Tuesday by B.C.'s Transportation Safety Board shows images from inside the sunken Queen of the North ferry during a dive by a remote-controlled submersible last month. The video shows the submersible's manipulator arms clearing the ferry deck of debris, breaking a bridge window to gain access and taking images of the controls. It also shows the submersible retrieving bridge computerized electronic systems that could shed light on what led to the fatal accident. The images from inside the vessel, which came to rest on the ocean floor a little over 1,400 feet were taken during a two-day dive by a submersible called an ROPOS (remotely operated platform for ocean science) operated by a Vancouver Island company, the Canadian Scientific Submersible Facility.
