An ex-employee of OceanGate, David Lochridge, has said the Titan submersible wasn't safe to dive and compared it to a "lemon", The New Yorker reported. This comes after the Titan tour submersible was destroyed in a catastrophic implosion, killing OceanGate CEO Stockton Rush and four others. Lochridge was reportedly fired after he warned of "safety" problems related to the submersible.
