Finally during the extreme acceleration the pressure gradient in the water was very high, and by increasing the initial pressure the differences would be relatively smaller. As the doctor so pedagogically had explained, "At sea level, the pressure is one bar. At 10 meters depth the pressure is 2 bar, and so the pressure is doubled; that is a 100% pressure increase. Given that 10 meter of water only gives 1 bar extra pressure, the difference between the depth of 90 meters and 100 meters is only 10%.
She stood in front of the launch bed. It was in many ways just a high-tech bed in a bathtub, filled with quite cold water. She shivered at the thought of getting in. Reluctantly she undressed, wondering if the water really needed to be that cold. She was only going to stay in it for about 5 minutes. Safety measures were always taken, and she knew that incase something went wrong, there would be more time to save her from suffocation if her body temperature was lowered.
Slightly shy she gave the camera a quick glance as she entered the watery launch bed. With both feet in, she mustered all her willpower to lie down in the cold water. "Two minutes!" the speaker called. In two minutes she would be lying in the cold water with water in her lungs, and in her ears and nasal cavities. She was lying on her back keeping her face barely above the surface, it tasted like sea water. The ‘drowner’ swung over her and stopped right above her face. This horrible instrument was much like a mechanical version of the aliens cubs illustrated in the old classical film by Aliens. The ‘drowner’ once she had placed it on her face, would clamp itself around her head and insert a tube into her lungs.
The voice from the speaker penetrated the water like a voice from another world. ”Twenty seconds! All personnel secure! Commence Launching sequence!” She waited. She could hold her breath for over 3 minutes this way. The drugs she had taken made her overwhelmingly relaxed as her body temperature dropped. "10...9...8...7...6...", the voice shouted. She could hear sirens in the background. "5...4...3...2...1", it was like the ground below her exploded. A sting of pain came from her right knee, and both her ears felt like someone had put a glowing iron into them. The rocket or projectile she was inside now accelerated up a 4.5 km magnetic driven shaft. Within three seconds she would have reached 3000 m/s or MACH 9. The force on her body was equivalent of 100 times the force of gravity. Once by it's self the projectile would start the rocket engine and continue to the space station. It was amazing how slow the three seconds passed, but then the pain disappeared as abruptly as it had appeared.
The water drained out of the bed, and as the water level sank down below her face, she breathed out. It was almost like throwing up, as the water poured out of her lungs. She coughed, and gasped for air, coughed out more water and gasped some more. Once again she was on her way into space.
