Cast & Crew
When an airplane or ship goes down, one of the first people called are the deep sea divers of the Mobile Diving and Salvage Unit (MDSU). Manned diving operations are dangerous missions -- whether doing scientific research or recovery missions -- and each trip requires precise calculations and physiological monitoring. The greatest threats are rip currents, torn suits and entanglement. Viewers follow the deep adventures of these divers as they undertake the business of a salvage operation involving one of the many downed aircraft in the Caribbean.
