Only three men have ever dared to take the plunge to the deepest part of the ocean. Diving that deep is an amazing feat with the possibility of great scientific discovery. However, there are a huge number of risks, including:
-Implosion -Penetrator Failure -Freezing
-Fire -Viewport Failure -Going adrift
-Hypothermia/hyperthermia
-Seafloor communications cable entanglement
-Hydrothermal vent-induced meltdown
