Emerging details on Titan sub reveal allegedly cavalier attitude toward safety

Experts had flagged safety problems with OceanGate's vessels much before the doomed journey that killed five people

As additional details emerge about the Titan submersible's deadly implosion in June, raising still more unknowns, concerns surrounding exploration company OceanGate Expeditions' allegedly cavalier attitude toward safety have come into sharper relief.

The doomed vessel reportedly dropped weights at some point during its descent; however, it is not known whether this was due to a routine part of descent or in an effort to abandon the doomed mission. All five Titan occupants died in the implosion.
