Reduced-gravity aircraft training avoids neutral-buoyancy training's drag problem (trainees are surrounded by air rather than water), but instead faces a severe time limitation: periods of sustained weightlessness are limited to around 25 seconds, interspersed with periods of acceleration of around 2 g as the aircraft pulls out of its dive and ...
Neutral buoyancy is used extensively in training astronauts in preparation for working in the microgravity environment of space. NASA and the Russian space program maintain facilities in which suited astronaut trainees interact with mock-up space hardware, with the assistance of scuba divers.
During training exercises, neutral-buoyancy diving is used to simulate the weightlessness of space travel. To achieve this effect, suited astronauts or pieces of equipment are lowered into the pool using an overhead crane and then weighted in the water by support divers so that they experience minimal buoyant force and minimal rotational moment ...

The Neutral Buoyancy Laboratory (NBL) has advantages in simulating a zero-gravity environment and reproducing the sensation of floating in space. The training method is achieved by constructing a low gravity environment through Maintaining the Natural buoyancy in one of the largest pools in the world.
The buoyancy compensator is used by ambient pressure divers using underwater breathing apparatus to adjust buoyancy underwater or at the surface within the range of slightly negative to slightly positive, to allow neutral buoyancy to be maintained throughout the depth range of the planned dive, and to compensate for changes in weight due to breathing gas consumption during the dive.
In the late 1980s NASA began to consider replacing its previous neutral-buoyancy training facility, the Weightless Environment Training Facility (WETF). The WETF, located at Johnson Space Center, had been successfully used to train astronauts for numerous missions, but its pool was too small to hold useful mock-ups of space station components of the sorts intended for the mooted Space Station ...
- Pre-familiarisation training course is conducted at EAC's Neutral Buoyancy Facility (NBF). The European Astronaut Centre (EAC) is in Cologne, Germany. Wikipedia article Yuri Gagarin Cosmonaut Training Center at Star City, Russia has some info about the neutral buoyancy water pool, but needs sourcing.
