STS-99 crewmembers Kavandi and Thiel suit up in EMUs for NBL training

S99-05721 (26 May 1999) --- Astronaut Gerhard P.J. Thiele, mission specialist representing the European Space Agency (ESA), awaits his helment as he stands on a movable platform. Minutes later, he and astronaut Janet L. Kavandi (not visible behind Thiele)were lowered into the nearby pool for an underwater training session at the Johnson Space Center's Neutral Buoyancy Laboratory (NBL), part of the Sonny Carter Training Center. Thiele and Kavandi have weights on the training version of their extravehicular mobility units (EMU) which help to provide neutral buoyancy in the deep pool. The astronauts were participating in a rehearsal of a contingency space walk.
