CPYRGHT:'
Safety comes first, not comfort, in the
manned submersibles that took part in
FAMOUS. Each houses its passengers in a
sphere, the best shape for withstanding
extreme water pressure.
Alvin's new titanium-alloy sphere, only
two inches thick, is identical to another that
withstood pressure to 22,500 feet when test-
ed by the Navy. Her self-contained variable
ballast system (above) depends on pumping
water in and out. Should Alvin become en-
tangled, her passenger capsule and conning
tower, or sail, can disengage and float to the
surface (right center).
