CBC News has spoken with two signatories to the letter, including Will Kohnen, chair of the Marine Technology Society's submarine group. There are only 10 submarines in the world that can go 4,000m or deeper and all of them are certified except the OceanGate, he told CBC News. Kohnen said the letter was never formally sent to Rush, however the two men spoke about the concerns in person, and Rush told Kohnen he'd received a leaked draft of the letter. The government of Newfoundland and Labrador told CBC News on Wednesday morning it has no responsibility over the Titan. They all follow rules, he told CBC News.
