Global National: June 21, 2023 | Underwater noises provide glimmer of hope in Titanic sub search

A Canadian military surveillance aircraft has detected underwater noises during its hunt for "Titan," the missing Titanic tourist submersible, providing a glimmer of hope for the public about the five people on board. Mike Armstrong explains how this discovery is impacting the operation and the vast size of the search area, while Eric Sorensen explains how sonar buoys, a technology first used during the Second World War, could play a critical role in the search.

Plus, it is the deepest successful sub rescue in history. Roger Mallinson was one of two men rescued from a Canadian-made submersible stuck at the bottom of the Atlantic Ocean in 1973. Redmond Shannon speaks with Mallinson about how he and his colleague Roger Chapman became trapped, how the pair survived and his empathy for the five people on board the "Titan."

The Royal Canadian Air Force (RCAF) has confirmed two crew members died in a training mission. The Chinook helicopter they were in crashed in the Ottawa River near Garrison Petawawa. Mackenzie Gray looks at why the military isn't saying much about the tragedy, how the tight-knit military community is in mourning, and how this isn't the first time the Chinooks have had issues.

Finally, the summer solstice coincides with National Indigenous Peoples Day in Canada, which marks cultural significance for First Nations, Inuit and Métis peoples. Melissa Ridgen looks at the history behind this celebration, and the ceremonies and events held across Canada.
