As Canadian and US authorities stepped up the search, previous questions about the safety design and development of the submersible by its owner, US-based OceanGate Expeditions, came to light. The Canadian military has dropped sonar buoys to listen for any sounds that might come from the Titan, and a commercial vessel with a remote-controlled deepwater submersible was also searching near the site, Frederick said.
Those aboard Titan for a tourist expedition that costs $250,000 per person included British billionaire Hamish Harding, 58, and Pakistani-born businessman Shahzada Dawood, 48, with his 19-year-old son Suleman, both British citizens. If the submersible experienced a mid-dive emergency, the pilot would likely have released weights to float back to the surface, according to Alistair Greig, a marine engineering professor at University College London. But absent communication, locating a van-sized submersible in the vast Atlantic could prove challenging, he said.
