DELTA DIVERS chronicles the adventures of some of the intrepid men and women who remove offshore oil platforms in the forbidding depths hundreds of feet beneath the surface of the Gulf of Mexico. It is high-risk, high-pay work suited to those with a mile-wide daredevil streak. Part-astronaut, part-roughneck—the hardhat diver is a breed apart. As commercial divers put it, diving is just the "road to the job." Hardhat divers do regulation blue collar work but in such an extreme environment that may as well be another planet—with only an “umbilical” tube of oxygen supply connecting them to our topside world.
