Nasa's female aquanauts

Five 'aquanauts' became the first women to front a mission for America's space agency, Nasa, in 1970. But their mission was underwater rather than in space. They spent two weeks being continuously monitored on camera in an undersea habitat. When they emerged from the experiment they were given a ticker tape parade and invited to the White House. Laura FitzPatrick has been speaking to Alina Szmant one of the aquanauts.
