Because the craft is excluded from the planetary gravity, the crafts are capable of fantastic acceleration and sharp turns in high speed without the crew inside the craft feeling any G-force effects.

由于飞船被排除来自行星的引力，飞船有能力作出色的加速，和高速急转弯，而船内的船员无感到任何G力的影响。

你会发现如果 a 等于 g,你下降的加速度就是重力加速度,也就是电梯的绳索断了,那时你会完全失重
