Investigation launched into Titan submersible tragedy and data examined.

Investigators will review voice recordings and data from the mother ship that carried the Titan submersible before it imploded, as part of an expanding international investigation into the incident that killed all five people aboard. The Transportation Safety Board of Canada is leading the investigation, which aims to find out what happened and why, and what needs to change to reduce the risk of such occurrences in the future. The Royal Canadian Mounted Police is also looking into whether criminal, federal, or provincial laws may have been broken. Questions have been raised about the Titan's design and safety measures.
