Carl Brashear had to pass a variety of strenuous physical examinations. One exam involved climbing a ladder with a set of weights strapped to his back equivalent to the weight of two scuba tanks. Eventually, after prolonged tests and diving exercises, Carl was put back on active duty. He stayed on active duty for 12 more years, and in 1970 Carl became the first black US Navy master diver.
It's good to talk.
