Watched Titan:The OceanGate Disaster in Netflix.
That disaster wouldn't have happened if they gave serious note to the carbon fiber used in the construction of the sub.It is clearly shown the malfunction caused due to popping of fiber when dived into the depth of the ocean.
Just giving complete ignorance to experts/ engineers warnings n concerns,the OceanGate CEO wanted to go into dive which caused the loss of five people including himself.
Great information about every aspects is shown in this documentary.Must watch...Though years went by,the loss of loved ones can't be reversed..Let them rest in peace..
Let's hope...in future...whatever discoveries are there to be revealed...it's good to experiment but nothing is above the life of a living being..
