Over Thanksgiving 50 years ago, three U.S. Navy volunteers spent their holiday (plus a few additional days) locked inside a steel test chamber like this one (at the Experimental Diving Unit, then in Washington, D.C.), which I hope shows up in the attached picture - vintage equipment, for sure, and the first in a series of simulated dives designed to figure out whether living in an undersea base would be physiologically feasible . . . or dangerous. . . or both. So happy anniversary to the Genesis experiments, which would lead to the first SEALAB . . .
