Space Technology Hall of Fame honors the deaf

According to NASA, a deaf engineer, in 1977, invented
the CI to help astronauts hear voices while weightless
in space.

Over the years, the hearing CI has become the deaf CI.

Rest is history.

Just hope the NASA has not forgotten the deaf,
without CI, that went through weightless experiments
in the late fifties/early eighties.
