In a media release issued shortly after 4 p.m. NT on Friday, the TSB said the investigation is "in accordance with the Canadian Transportation Accident Investigation and Safety Board Act and international agreements."
As the investigative authority of Canadian vessels, the TSB said it will conduct "a safety investigation regarding the circumstances of this operation conducted by the Canadian-flagged vessel Polar Prince."
Does anyone know what kind of responsibility the Polar Prince would have to make sure the sub operation wasn't essentially a harebrained scheme? I have no idea how that works, but I think the seriousness of the investigation would probably hinge on that.
